v1.6
71f64a8

This release introduces several modifications to the config file.
You will need to upgrade your old config files manually or using
source_spec -U CONFIG_FILE_NAME.

This release requires at least Python 3.6.

A lot of effort has been devoted to improve the documentation.
Please check it out on https://sourcespec.readthedocs.io/

Input/output

  • QuakeML output (when using QuakeML input)
  • Command line option --run-id to provide a string identifying the
    current run (see pull request [#6])
  • Write SourceSpec version to parfile
  • Write SourceSpec version and run complete time to SQLite file
  • Write author and agency info (if specified) to output files, figures and
    HTML report
  • HTML page for misfit plots (when using grid search or importance sampling)
  • Station table in HTML report is now sortable (and its header remains fixed)!
  • Reduce PNG figures file size, while improving their resolution 😃
  • Removed option to read event information and traces from a pickle file
    (rarely used)

Processing

  • Support for P-wave spectral inversion (see pull request [#9])
  • It is now possible to provide different vp and vs velocities, close to the
    source and close to the stations (see the new config options above and
    issue [#5])
  • Possibility to choose a geometrical spreading model between
    (see issue [#8]):
    • rⁿ (default: n=1 – body waves)
    • Boatwright et al. (2002): "r" below a cutoff distance, frequency-dependent
      above the cutoff distance
  • Use travel time to compute quality factor from t* (and viceversa)
    (see issue [#5])
  • Compute travel time from pick and origin time, when possible
    (see issue [#10])
  • Warn if noise window ends after P or S arrival

Post-Inversion

  • Subtract the integral of noise spectrum from the integral of signal spectrum
    when computing radiated energy, under the hypothesis that energy is additive
    and noise is stationary

Config file

  • Config parameter paz has been removed and merged into station_metadata
  • Config parameters vp and vs have been renamed to vp_source
    and vs_source (see issue [#5])
  • New, optional, config parameter vp_stations and vs_stations
  • Config parameter pre_p_time and pre_s_time have been renamed to
    noise_pre_time and signal_pre_time, respectively (see pull request [#9])
  • Config parameter rps_from_focal_mechanism renamed to
    rp_from_focal_mechanism (see pull request [#9])
  • New config parameter: geom_spread_model (see issue [#8])
  • Config parameters PLOT_SHOW, PLOT_SAVE and PLOT_SAVE_FORMAT are now
    lowercase (plot_show, plot_save and plot_save_format)
  • New, optional, general config parameters for specyfing author and agency
    information. This information is written to output files and figures,
    if specified
  • New config parameter, event_url, to link the event page from the HTML
    report
  • Removed DEBUG config parameter
  • Parameters from GENERAL PARAMETERS section reorganized into a new
    section called TRACE AND METADATA PARAMETERS
  • Some parameters from INVERSION PARAMETERS moved into a new section
    called SPECTRAL MODEL PARAMETERS

Bugfixes

  • Fix for not working weighting options: frequency and no_weight
  • Fix for negative weights occasionally generated by interpolation
  • Fix bug when event coordinates are written into sqlite as binary blobs
