Note
Note that the default config parameters are suited for a M<5 earthquake recorded within ~100 km. Adjust win_length
, noise_pre_time
, the frequency bands (bp_freqmin_*
, bp_freqmax_*
, freq1_*
, freq2_*
) and the bounds on fc
and t_star
, according to your problem.
If you have seismic recordings in miniSEED format (e.g., traces.mseed
), metadata in StationXML format (e.g., station.xml
) and event information in QuakeML format (e.g., event.xml
), then:
- Generate a config file via
source_spec -S
; - Edit the config file variable
station_metadata
to point tostation.xml
file; - Run
source_spec -t traces.mseed -q event.xml
.
If you have seismic recordings in SAC format (e.g., in a directory named sac_data
), metadata as SAC polezero (PAZ) (e.g., in a directory named paz
) and event information in any format, then:
- Generate a config file via
source_spec -S
; - Edit the config file variable
station_metadata
to point to thepaz
directory; - Generate a sample
source_spec_event_file:SourceSpec Event File
usingsource_spec -y
; this will create a file namedssp_event.yaml
; - Edit the file
ssp_event.yaml
with your event information; - Run
source_spec -t sac_data -H ssp_event.yaml
.
After successfully installed SourceSpec (see installation:Installation
), you can get help on the command line arguments used by each code by typing from your terminal:
source_spec -h
(or source_model -h
, or source_residuals -h
).
source_spec
and source_model
require you to provide the path to seismic traces via the --trace_path
command line argument (see file_formats:File formats
).
Information on the seismic event can be stored in the trace header (SAC format), or provided through a QuakeML file (--qmlfile
) or, alternatively (--hypocenter
), through a source_spec_event_file:SourceSpec Event File
, a HYPO71 file, or a HYPOINVERSE-2000 file. See file_formats:File Formats
for more information on the supported file formats.
source_spec
and source_model
require a configuration file. The default file name is source_spec.conf
, other file names can be specified via the --configfile
command line argument.
You can generate a sample configuration file through:
source_spec -S
Take your time to go through the generated configuration file (named source_spec.conf
): the comments within the file will guide you on how to set up the different parameters.
