Description

Changelog
  • core.match_filter
    • match_filter:
      • Provide option of exporting the cross-correlation sums for additional later analysis.
  • core.match_filter.party.write
    • BUG-FIX: When format='tar' is selected, added a check for .tgz-file suffix before checking the filename against an existing file. Previously, when a filename without '.tgz'-suffix was supplied, then the file was overwritten against the function's intention.
    • Add option overwrite=True to allow overwriting of existing files.
  • core.match_filter.party.read
    • BUG-FIX: Ensure wildcard reading works as expected: #453
  • core.match_filter.party.rethreshold:
    • added option to rethreshold based on absolute values to keep relevant detections with large negative detect_val.
  • core.lag_calc:
    • Added option to set minimum CC threshold individually for detections based on: min(detect_val / n_chans * min_cc_from_mean_cc_factor, min_cc).
    • Added the ability of saving correlation data of the lag_calc.
  • utils.mag_calc.calc_b_value:
    • Added useful information to doc-string regarding method and meaning of residuals
    • Changed the number of magnitudes used to an int (from a string!?)
  • utils.mag_calc.relative_magnitude:
    • Refactor so that min_cc is used regardless of whether weight_by_correlation is set. See issue #455.
  • utils.archive_read
    • Add support for wildcard-comparisons in the list of requested stations and channels.
    • New option arctype='SDS' to read from a SeisComp Data Structure (SDS). This option is also available in utils.clustering.extract_detections and in utils.archive_read._check_available_data.
  • utils.catalog_to_dd
    • Bug-fixes in #424:
      • only P and S phases are used now (previously spurious amplitude picks were included in correlations);
      • Checks for length are done prior to correlations and more helpful error outputs are provided.
      • Progress is not reported within dt.cc computation
    • write_station now supports writing elevations: #424.
  • utils.clustering
    • For cluster, distance_matrix and cross_chan_correlation, implemented full support for shift_len != 0. The latter two functions now return, in addition to the distance-matrix, a shift-matrix (both functions) and a shift-dictionary (for distance_matrix). New option for shifting streams as a whole or letting traces shift individually (allow_individual_trace_shifts=True).
  • utils.plotting
    • Function added (twoD_seismplot) for plotting seismicity (#365).
