v0.1:

combined time series codes that I had in different projects:

  • crawtools

    • decimate
    • spectral

  • rptransient: All except:

    • decimate (used one from crawtools)
    • read_mseed (changed to independent function

  • wayne_obstools

    • fir_corr => timeseries?
    • Peterson_model, plot_PPSD, plot_response, plot_sensitivity

0.2:

Made sure that all of the equations correspond to equations in Bendat&Piersol (2010). Verified that we now get as good of results as the old Matlab code. Set up testing for the different sub-modules. Probably changed some method call parameters. Created a readthedocs page.

0.3:

MAJOR

  • SpectralDensity:
    • Added required argument window_s to creator
  • Renamed TransferFunction properties:
    • values to frf (frequency response function)
    • uncert to uncertainty
    • channels to channel_names
  • TimeSpans:
    • Now created using spans by default
  • DataCleaner
    • always renames cleaned channels, putting information in the location code slot (second from last element in string separated by '.'s)
    • Removed unused fast_calc parameter from clean_sdf()

BUGFIXES

  • Changed SpectralDensity.from_stream() z_threshold to apply to log10(spectra) rather than (spectra) (otherwise, "standard" zthreshold=3 rejects more than half of typical data)
  • TransferFunction()
    • now provides a "frequency response function" (frf) and a corrector (for data cleaning): the two are the same only if all noise is on the output channel (see Bendat and Piersol chapter 6)
    • fixed (and simplified) calculation of uncertainty
  • DataCleaner uses TransferFunction's corrector property.

MINOR

  • SpectralDensity:
    • Added arguments ts_starttime and ts_endtime to creator
    • Added ``used(), unused()` methods and `window_seconds` property
    • autospect() and .crossspect() now accept wildcards in channel names
    • Added channel_name() method
    • Added **fig_kw to plot_*() methods
  • TimeSpans:
    • Added spans property
    • Added invert() method
    • plot() can include a trace or stream
  • Updated documentation
  • DataCleaner:
    • Created CleanerString class to help with channel names

0.3.1

Fix `TransferFunction` errorbar plotting bug

0.3.2

Change `MANIFEST.in` to recursively include subfiles/directories of decimate/

0.3.3

- Decimator.decimate() now returns same data.dtype by default
- TransferFunction now accepts wildcards for out_chan names
- Added 'outfile' to TransferFunction.plot()
- Added TransferFunction.put_response()

0.4

  • Renamed TransferFunction to ResponseFunction, changed internal and method names to correspond:

    • .response -> instrument_response
    • .frf -> .value
    • .frf_wrt_counts -> .value_wrt_counts
    • SpectralDensity.channel_response -> SpectralDensity.channel_instrument_response
    • SpectralDensity.put_channel_response -> SpectralDensity.put_channel_instrument_response
    • SpectralDensity.init(response=) -> SpectralDensity.init(instrument_response)

  • Internally renamed tiskit to tiskitpy

0.4.1

Rewrote tracking of cleaning steps, a lot of internal work, including
new classes, but should be invisible when using the command-line codes
and mostly invisible when using the API.

0.5

  • Added channel identification by tiskitpy_id, which includes cleaning information. The tiskitpy_id for uncleaned data is the seed_id.
  • Added class CleanedStream and revised the guts of several classes, including renaming SpectralDensity.channel_names to SpectralDensity.ids.
  • CleanRotator class now has a property variance_reduction which gives the variance reduction obtained during init()
  • Added SpectralDensity.plots() and .plots_coherences(), to compare multiple SpectralDensity objects
