[Unreleased]

empty

[2021.04.02]

Added

  • RectangularSource: added opening_fraction to model tensile dislocations
  • New command line option for jackseis: --record-length
  • Timing definition offsets can now take % as suffix to scale phase traveltimes relatively.
  • New plot function to show radiation pattern / azimuthal distribution of directivity effects for synthetics.
  • Snuffler: load StationXML via menu.
  • io.mseed: Adding option for STEIM2 compression.
  • Jackseis: Adding --output-steim option to control compression. Default compression changed to STEIM2.
  • YAML files can now include other YAML files, when loaded through guts.
  • Moment tensor objects can now also be initialized from east-north-up coordinates.

Fixed

  • Fix plotting issues in cake.
  • Update Geofon catalog to handle MTs correctly after Geofon web page update.
  • Fix typos in STA/LTA documentation.
  • Fomosto PSGRN/PSCMP backend: improved control of modelling parameters, fixes some accuracy issues, regarding the spacial sampling interval.
  • Fomosto PSGRN/PSCMP backend: fixed scaling of isotropic GF components
  • Improved handling of differing sampling rates and interpolation settings when modelling multiple targets in gf.Engine.process.
  • PyQt compat issues with MacOS Big Sur.
  • Fix of gf.SFSource.discretize_basesource.

Changed

  • GmtPy now forces PDF version 1.5 when producing PDFs (newer PDFs caused problems when included in XeLaTeX).
  • QuakeML: Not strictly requiring preferred origin to be set anymore when extracting Pyrocko event objects.
  • Snuffler now asks for confirmation when the user attempts to close the window.

[2020.10.26]

Fixed

  • Fix errors with corrupt WADL returned by GEONET FDSN web service.
  • Fix cake crashes related to the --distances argument on newer NumPy/Python3.8.

Changed

  • Changed default of demean argument to Trace.transfer from False to True, to be consistent with the behaviour before the introduction of that flag.

[2020.10.08]

Added

  • Support for rotational seismograms in GF stores and Fomosto QSSP2017 backend.
  • Trace objects now support serialization to YAML and inclusion into Guts based objects.

Fixed

  • Fix incorrect conversion from displacement to velocity and acceleration in seismogram synthesis in pyrocko.gf. The problem occured when quantity='velocity' was selected in a pyrocko.gf.Target with a GF store with stored_quantity='displacement'. The returned amplitudes were incorrect except for the case of 1 Hz GFs.

Changed

  • Installation of prerequisites is now possible with a separate script install_prerequisites.py rather than through setup.py install_prerequisites.

[2020.08.18]

Added
