  • fix a regression introduced by #3306 which lead to some network errors not
    getting raised as an FDSNException but some low-level exceptions like
    AttributeError, which in turn caused problems in Mass Downloader (see
    #3513)
  • mass downloader: Use the download(threads_per_client) value for
    StationXML downloads. (see #3678)

    results. See docs for get_info() for information how to see the excluded
    stations (see #2808)
• obspy.imaging.beachball:
  • allow isotropic component to be plotted. Ensure explosions and
    implosions plot fully colored/uncolored, and that the correct

    np.frombuffer to increase efficiency when data is already in memory. (see
    #3622)
  • new routine to spread a time interval progressively across all mseed
    blockettes in a file (see #3271)

    will now by default be rounded to microseconds before taking the
    reciprocal to set the sampling rate. This can be deactivated using
    "read(..., round_sampling_interval=False)" (see #3408)
  • fix writing SACPZ END tag when empty (open ended) (see #3696)

    but SC3ML still works as a FORMAT kwarg (for now)
  • add option to write different SCML catalog versions
  • update/refresh XSL files to latest (2025)
    Fixes origin/confidenceEllipsoid conversion. The unit for
    'semiMajorAxisLength', 'semiMinorAxisLength' and
    'semiIntermediateAxisLength' is already meter and does not need a
    conversion.

    not exist with XSEED Parser (see #2686)
• obspy.signal:
  • PPSD: performance improvement in init: faster frequency array
    calculation (see #3644)
  • PPSD: Changed the moment instrument responses are calculated by evalresp:
    they are now preloaded at PPSD instantiation time, and no longer
    calculated for each time window (see #3589)
  • all butterworth filters: correct zero-phase filtering of 2-d arrays and
    filtering along non-default axis of 2-d arrays (see #3291)

    numpy code. Speedup of roughly factor 10 for integer data and 1.5 for
    floating point data. (see #3621)
  • Fix filter construction (_filter) where freqs has len 1, linked to
    numpy 2.4.0 deprecation expiration. (see #3668)
  • Add warnings.catch_warnings for spectral_estimation tests, linked to
    a new numpy 2.4.0 deprecation. (see #3668)

    to install odrpack if they have SciPy >= 1.19.0 (see #3676, #3662)

ObsPy 1.4.2 (doi: 10.5281/zenodo.15309143)

Changes:

• General:
  • add support for numpy v2.0 (see #3461)
• obspy.core:
  • util: removed old and outdated 'CatchWarnings' context manager in favor of
    the better 'CatchAndAssertWarnings' context manager (see #3452)
• obspy.clients.fdsn
  • make sure to use a copy of DEFAULT_SERVICES when initializing a client
    instance while skipping service discovery, to avoid accidental changes to
    DEFAULT_SERVICES (see #3493)

ObsPy 1.4.1 (doi: 10.5281/zenodo.11093256)

Changes:

• obspy.core:
  • fix a bug in response calculation with non-SI input units. With e.g.
    "nm/s" as first stage input units (which is unusual, though), the
    amplitude of the frequency response was calculated wrongly, not taking
    into account the scaling factor needed to get from "nm/s" to "m/s". In
    general if this bug would have been encountered before it should have led
    to quite obviously wrong results, since it would lead to values that would
    have been off by at least two orders of magnitude (e.g. in case of "cm/s")
    or even up to nine orders of magnitude (e.g. in case of "nm/s").
    (see #3369)
  • fix a bug in Stream.select(inventory=...) (see #3282)
  • fix a problem in Stream.plot() failing to remove the "min-max-plot zoom
    warning" when interactively zooming into and then again out of a plot with
    reduced number of points plotted with matplotlib >=3.6 (see #3318)
  • fix an issue with Stream.rotate() when there are dots in e.g. station code
    (see #3373)
• obspy.clients.fdsn:
  • update URLs for FDSN web services raspberryshake, ISC and LMU (see #3264,
    and #3413)
  • properly include server response in error messages on bad requests (see
    #3306)
  • IRIS/Earthscope: fix all "catalogs" and "contributors" being suffixed with
    '\n ' (see #3438)
• obspy.clients.nrl:
  • better handling of individual stages units when combining sensor and
    datalogger response from a full downloaded offline version of the new NRL
    v2 (see #3315, #3395)
  • add support to use new categories "integrated" and "soh" in new NRL v2
    (see #3315)
• obspy.clients.seedlink:
  • avoid unnecessary calls to "get_info()" on waveform requests without
    wildcards (see #3232)
• obspy.imaging:
  • fix a bug that raised an error when plotting beachball patches with
    routine "beach" with providing an existing axes instance (for proper
    scaling) and saving to vector graphics as pdf/eps (see #2887)
  • fix a problem in Stream.plot() failing to remove the "min-max-plot zoom
    warning" when interactively zooming into and then again out of a plot with
    reduced number of points plotted with matplotlib >=3.6 (see #3318)
  • fix some issues with bad x-tick positioning and labeling in dayplots
    (see #3361)
  • fix a bug in Stream.plot() where the plotting method argument (e.g.,
    'fast', 'full') was ignored for section-type plots
• obspy.io.gcf:
  • Fixed an issue in algorithm to split and encode last few data into GCF
    blocks (see #3252)
• obspy.io.sac:
  • Fix writing SACPZ from poles and zeros stages with Hertz transfer function
    type. SAC is expecting the SACPZ data to be in radians/s (see #3334)
• obspy.io.wav:
  • Fixed reading of stereo wav files (see #3399)
• obspy.io.win:
  • Fixed three bugs when reading 0.5 byte datawide (see #3310)

  • Fixed reading SEED frequency-amplitude-phase response lists that are
    spread out over multiple blockettes (see #3277)
  • Fix reading uncertainties of poles/zeros complex numbers (see #3401)
• obspy.io.zmap:
  • Fix writing events with origins that have no depth or depth errors given
    (see #3343)
• obspy.signal:
  • PPSD: Fix some time slices getting skipped if sampling rate does not align
    well with the length of one PSD slice. (see #3387)
• obspy.taup:
  • bugfix to allow calculations for a model with no discontinuities
    (see #3070, #3244)

ObsPy 1.4.0 (doi: 10.5281/zenodo.6645832)

Changes:

• obspy.core:
  • Minimum supported Python version is now 3.8 (see #3081, #3087)
  • Minimum supported dependency versions are now numpy 1.20, scipy 1.7 and
    matplotlib 3.3 (see #3081, #3087)
  • response: avoid reporting all unkown units (e.g. "RAD/S") to evalresp as
    displacement ("DIS") which with default value for "output" ("VEL") leads
    to evalresp adding a differentiation during response calculation. Instead
    report undefined unit, which makes evalresp use response as is and
    essentially ignoring "output" parameter (see #2945)
  • Improved expanded channel information in string representation of Station,
    e.g. when displaying station in IPython shell (see #3024)
  • limit length of list which records processing info (see #2882)
  • map plots: fix initial map setup, properly pass through user specified
    options, like "projection" etc (see #3191)
• obspy.clients.fdsn:
  • update URL for NCEDC to https (see #3203)
  • add all valid parameters to get_stations_bulk, e.g. geographical
    constraints (see #3140)
  • do not use autodiscovery of file format in get_stations, unless "format"
    is set to something we do not recognize (see #3138)
  • fix a bug in routing client that made any request made error out when
    "debug=True" was set (see #3214)
  • fix raising FDSNTooManyRequestsException when server rejects request due
    to rate limiting, due to a bug instead a TypeError was raised (see #3219)
• obspy.clients.seishub:
  • submodule removed completely, since it is outdated and not even test
    servers have been running for years (see #2994)
• obspy.db:
  • submodule removed completely, since mostly being used in discontinued
    seishub server (see #2994)
• obspy.imaging:
  • spectrogram: change the computation for default window length if not
    specified to give useful values for sampling rates much higher or lower
    than 100 Hz (see #3093)
  • spectrogram: better exception type and messages when input signal is too
    short (see #3093)

  • new module for reading data from the Apollo missions stored in ALSEP
    format (see #3156)
• obspy.io.nlloc:
  • avoid mangling channel/component code when writing nonlinloc phase file,
    just write full channel code unchanged into nonlinloc's "component" field
    (see #3223)
  • fix reading nonlinloc hypocenter files written by newer nonlinloc
    versions, data parsed into Arrivals was wrong (see #3223)
  • read geometrical station azimuth instead of ray takeoff azimuth from
    hypocenter. This is more robust (ray takeoff values sometimes not accurate
    at all) and also follows more the QuakeML documentation that states
    "Azimuth of station as seen from the epicenter" which implies a simple
    geometrical calculation (see #3224)
  • ignore ray takeoff dip if the stated quality for it is "0 - unreliable".
    our example data show that values can be blatantly wrong when quality is
    reported as "0" (see #3224)
  • write timing error as "0.0" if it is not set on a pick, as recommended by
    nonlinloc's author (see #2371, #3224)
• obspy.io.nordic:
  • add support for writing multiple amplitudes for one pick (only new format)
    and writes some amplitude lines more compact (see #3075, also #2814)
  • add full support for reading and writing apparent velocity and backazimuth
    with new nordic format (see #3075)
  • fix comments on angle of incidence vs. takeoff angle (What is called
    angle of incidence in Seisan is the same as what is usually referred to as
    takeoff angle, see #3075)
  • add function to check whether phase is valid IASPEI phase in Seisan (#3075)
  • full support for writing high-accuracy origin line (see #3075)
• obspy.io.sac:
  • expose a keep_sac_header flag to the write plugin, which allows users
    to write a "fresh" SAC header, instead of attempting to merge information
    from an old SAC header, if one exists. (see #2760)
  • fix writing SACPZ when a channel's sensor filed is unset (see #3187)
• obspy.io.seiscomp:
  • update SeisComP 0.11 and 0.12 schema to potentially speed up sc3ml to qml
    event catalog conversions (see #3216 and SeisComP/common#74)
• obspy.signal:
  • coincidence trigger: improve speed of template matching and less memory
    usage (see #3104)
  • Baer picker: fix a bug that could cause crashes on certain versions of
    libffi (see #3183)
  • polarization analysis: fix calculation of timestamps of the resulting
    values (see #3211)
• obspy.taup:
  • add option "indicate_wave_type" to distinguish S waves in ray paths
    plot by using wiggly lines for shear waves (see #3047)
  • improved accuracy of ray paths by change of root-finding algorithm
    in SeismicPhase.refine_arrival (see #3064, #3096)
  • improved accuracy of travel time estimates by using theta function
    (see #3068)
  • add support for models without a core or inner core
    (see #1200, #1423, #2086, #2192, #2390, #3070)
  • add support for a wider range of diffracted phases, like SedPdiffKP
    (see #3085) and PKdiffP (see #3095)
  • allow rapid travel time plotting in plot_travel_times by using
    precalculated travel times (see #3092)
  • return pierce points for any depth (see #1742, #3072)
  • bug fix for rays which cannot turn due to low velocity at bottom
    of layer (see #3080)
  • add some checks for bad phases, so "ScScS" is not allowed
    (see #2774, #3082)
  • bug fix for sources within high slowness regions (see #2976, #3100)

ObsPy 1.3.1 (doi: 10.5281/zenodo.7193374)

Changes:

• obspy.core:
  • Fix exclusion of magnitude 0 events in Catalog.filter (see #3105)

  • Fix reusing Catalog/Inventory map plots, i.e. doing multiple cartopy plots
    with these objects into the same axes (see #3018)
  • Fix Stream.rotate with multiple-station or multiple-event Streams (see
    #2623, 3155)

  • fix iso8601 regex for issue #2868 to cope with day 360 properly
  • fix crash when resampling very short traces (see #2926)
  • response list stages: do not raise an exception if response calculation
    involves extrapolation outside of frequency range defined by the response
    list stage but rather only show a warning. raising an exception is the
    safe route but it also prevents valid calculations as it is up to the user
    to make sure that signal spectrum is properly suppressed in those
    frequency ranges outside of the valid response information (see #2988)
  • fix a bug while checking for valid URI syntax when setting identifiers on
    inventory type objects (see #2905)

    (see #2739, #2932)
  • update RESIF URL mapping to use http and add RESIFPH5 (see #2938)
• obspy.clients.filesystem:
  • add get_waveforms_bulk() method to SDS client (see #2616, #2626)

  • add read support for horizontal and vertical origin uncertainty (see #2687)
• obspy.io.kinemetrics:
  • adds the apply_calib argument to the read_evt method to allow
    obtaining the raw data bits stored in the evt file (see #2582), note this
    changes the default (wrong!) behaviour, by default the data returned will
    be the NOT corrected ones. When passing apply_calib=True, the
    calibration factor will be used.
• obspy.io.nordic:
  • add read and write support for New Nordic format (see #2814)
  • fix bug where negative magnitudes were not read properly
  • fix bug where empty hours / minutes / seconds were not read as zero
  • fix bug where lat/lon-errors were read as lon/lat
  • fix bug where origin-error was written with RMS rather than time_error

    (see #2678)
  • properly take into account native system byteorder, should fix reading
    rt130 data on big endian systems (see #2678)

• obspy.io.sh:
  • fix appending traces to existing Q file (see #2870)
• obspy.io.xseed:
  • fix a bug reading SEED blockettes 48 and 58 which was likely never
    encountered (see #2668)
  • Properly read a given value of 0.0 in station elevation and not replace it
    with bogus value (see #2763)

Changes:

• obspy.core:
  • Inventory objects have been adapted to StationXML 1.1 for details on
    changes see #2510 and
    https://github.com/FDSN/StationXML/blob/master/Changes.md
  • Fixed import of custom plugins (see #2423)
  • Fixed "==" comparison for Stream and Trace which was very slow in case of
    traces with >1e6 samples (see #2377)
  • Added almost_equal method for Stream and Trace classes (see #2286).
  • Casting FDSN identifiers to strings upon setting in the stats dictionary
    (see #1997).
  • UTCDateTime objects will now always evaluate equal if their string
    representations are equal (see #2049).
  • UTCDateTime objects now issue depreciation warnings when setting any
    attributes outside of init, or comparing UTCDateTime objects with
    different precisions (see #2077).
  • UTCDateTime objects can now accept hour, minute, second, and microsecond
    values greater than their normal limits by setting the strict keyword
    argument to False (see #2232).
  • Fixed UTCDateTime(..., julday=366) for non-leap years. This was returning
    January 1st of the next year in case of non-leap years being used. Now it
    properly raises an out-of-bounds ValueError (see #2369)
  • When reading StationXML/SC3ML, make sure to properly read empty string
    fields as empty strings instead of "None" (see #2519 and #2527)
  • Better ISO8601 detection for UTCDateTime objects and UTCDateTime(...,
    iso8601=False) now completely disables ISO8601 handling (see #2447)
  • Added replace method to UTCDateTime class (see #2077).
  • Added remove method to Inventory class (see #2088).
  • Added id property to WaveformStreamID (see #2131).
  • Added str and repr_pretty method for Comment class (see #2115)
  • Added eq to QuantityError so empty instances equal None (see #2185).
  • Reworked the event scoped resource identifiers for the event classes
    hopefully fixing all edge-cases (see #2091).
  • Added a hook to allow users to customize finding objects for
    resource_ids which are not found via the normal means (see #2279).
  • Calling Stream.write(...) on an empty stream will now raise an
    ObsPyException consistently across all I/O plugins (see #2201)
  • Stream.get_gaps() will now properly report gaps within Traces that
    have masked arrays (i.e. Traces that have been merged without a fill
    value, see #2299 and #2300).
  • Added copy method to Inventory class (see #2322).
  • The Response.recalculate_overall_sensitivity() method now accepts integers
    (see #2338, #2343).
  • Added wildcard and url support to read_inventory (see #2326).
  • Modified stream.get_gaps() to deal with overlaps correctly (see #1403)
  • Added option "label_epoch_dates" to Inventory/Network.plot_response() to
    optionally add channel epoch start/end dates to legend labels (see #2309)
  • Deprecated the convert_id_to_quakeml_uri, regenerate_uuid, and
    get_quakeml_uri methods of the ResourceIdentifier class (see #2303).
  • Added get_quakeml_uri_str and get_quakeml_id methods to the
    ResourceIdentifier class (see #2303).
  • New method to create response objects directly from poles and zeros (see
    #1962).
  • Added Stream.stack method (see #2440).
  • Added a component field to the Stats object which allows to get and set
    the last character of the SEED channel (see #2484).
  • Fixed a bug in Stream.plot(type='section', reftime=..., ...) that caused
    wrong relative start times of traces relative to given reftime (see #2493)
  • Fixed a Windows-specific path case issue in a helper function that returns
    a list of untracked files in the git repository (see #2296)
  • Fix a bug that was causing an exception being raised in Response.plot()
    because a float was being passed down to numpy.linspace as length of array
    (see #2533)
  • Geographic select of inventory/network/station (see #2515)
  • Select traces in Stream based on an Inventory (see #2531)
• obspy.clients.fdsn:
  • Add new _discover_services boolean flag to the Client, which allows the
    Client to skip the initial services query at instantiation. This can
    reduce the load on service providers, but skips checks against unsupported
    query parameters.
  • Adding more location codes to the default priority list in the mass
    downloader (see #2155, #2159).
  • The mass downloader now raises a warning if all channels from a station
    have been deselected due to the default location priorities setting. This
    is a pure usability improvement as it has been confusing users
    (see #2159).
  • Make sure that streams fetched via FDSN are properly trimmed to user
    requested times if data center serves additional data around the start/end
    (see #1887, #2298)
  • Fix a problem that could spam subprocesses that were not closed in routed
    clients (see #2342 and #2344)

  • Add method "get_info()" to fetch information on what
    networks/stations/locations/channels are served by the seedlink server
    (see #2405)
  • "get_waveforms()" can now be used with '*' and '?' wildcards in any part
    of requested SEED ID, i.e. network, station, location and channel (see
    #2405)
• obspy.clients.seishub:
  • Properly handle fetching poles and zeros in presence of multiple metadata
    files for a given station (see #2411)
• obspy.geodetics:
  • New utility function inside_geobounds() to check whether an object is
    inside a geographic bound (see #2515)
• obspy.imaging:
  • obspy-scan can now be used with wildcarded SEED IDs when specifying what
    to plot after scanning data (see #2227)
  • Fix a problem in Scanner when loading npz on Python3 that was written on
    Python2 (see #2413)
  • Fix an issue that could make small landmasses not get plotted in basemap
    plots (see #2471, #2477)

    file without any data records (see #2534 and #2535)
  • Add ability to write int64 data to mseed if it can safely be downcast
    to int32 data, otherwise raises ObsPyMSEEDError. (see #2356)
  • The recordanalyzer can now detect calibration blockettes 300, 310,
    and 320 (see #2370).
  • Can now write zero sampling-rate traces. (see #2488, 2509)
