Changelog

All notable changes to Grond are documented in this file.

The format is based on Keep a Changelog.

Unreleased

Added

• grond go utilises --threads arguments for various tasks.
• InSAR plots improved, now plotting ‘best’ and ‘mean’ // Improvements

Fixed

• Improvements in documentation and examples.
• satellite.plot degree axis offset and close-up scaling for point sources.

[1.3.2] 2019-07-03

Added

• Can now run target balancing with a fixed magnitude (reference event) for automatic removal of stations providing unreasonably large misfits (use_reference_magnitude and cutoff in TargetBalancingAnalyserConfig).
• Add possibility to export only results from runs matching given criteria. At the moment, it is possible to select by rundir tag (grond export --selection).

Fixed

• Corrected time window calculation in NoiseAnalyser
• Plots not using harvest subset.

[1.3.1] 2019-06-08

Added

• Allow controlling number of threads in grond report with --threads

Changed

• Default number of threads used in grond go and grond report is now 1. Setting both together, --parallel and --threads, to values higher than 1 may currently cause hangs.
• Improved control on threading utilization.

Fixed

• Repaired grond report and grond plot location_mt which were broken in v1.3.0.

[1.3.0] 2019-06-04

Added

• Added Covariance weighting from SatelliteTarget and GNSSTarget.
• Added new Volume source (VLVD).
• Added SVG as grond plot export format.

Changed

• Consistent utilisation of ModelHistory for plots and results.
• MTLocationPlot supports Gamma scaling (misfit^gamma).
• SatelliteTarget speeds up bootstrapping by multi-threading.
• Envronment can be initialised from ProblemConfig.
• Improved: grondown downloading seismic wave forms.

[1.2.0] 2019-02-19

Added

• Waveform targets: switch to change to acceleration / velocity fitting.
• Waveform targets: include / exclude stations by pattern on target-group level.
• Option to export list of stations used in one or more setups (grond check --save-stations-used=<filename>).
• Can now handle GNSS stations lacking complete set of component orientations.
• Noise analyser: added possibility to except stations with high S/N ratio from removal due to high pre-event noise.
• Improved unit tests.
• Report archive generation can now be skipped via command line flag or report configuration setting.
• CMT problem: can now switch between different source time functions.
• Added workaround switch for "cannot project traces with displaced sampling" issues.

Changed

• Transparent event loading and checking.
• Noise analyser: target groups are now handled independently. Each group now uses its own threshold in weeding mode.
• Improved error handling (grond check, instrument responses,
• Only exclude waveform targets when distance_min constraint is given in problem_config.
• Improved method chapter in documentation.

Fixed

• Waveform fit plots: fix crashes while plotting results from joint inversions.
• Satellite fit plots: fix bug in source outline drawing
• Waveform targets: fixed handling of channel epochs from StationXML for channel orientations.
• Station plots: fixed problems with empty target groups.
• No more MPL warnings ‘too many open figures’ when creating sequence plots; the plots are now created one by one.
• Report: fix dsiplay issue with inaccessible elements in left navigation.
• Fixed crash when starting_point setting in highscore optimiser is set to mean.

[1.1.1] 2019-02-05

Fixed

• Bug in volume point source plot causing crashes.

[1.1.0] 2019-01-22

Added

• New VolumePointProblem to optimise magmatic and volcanic processes.
• New problem config sections in grond init.

Changed

• Documentation of problems configurations are now centralised at src/data/snippets.
• Output of grond init list.

Fixed

• Bug in GNSSMisfitTarget.
• Plotting in GNSS plotting functions.
• Highscore optimiser logging output
• Satellite plot: Setting geographical aspect ratio for LatLon data
• GNSS Plotting function

[1.0.0] 2019-01-07

Added

• Cluster analysis on result ensemble with grond cluster.
• Plotting of cluster analysis results in jointpar, mt_decompostion, and mt_fuzzy plots.
• User can now add self-defined labels to a run dir (grond tag). The labels are shown in the report list.
• The optimiser’s acceptance and choice history is now dumped and plotted.
• Added station distribution plot for seismic and GNSS stations.
• Installation instructions for Anaconda and pip.

Changed

• Parallelized grond report.
• Rewritten grond init to deliver examples and commented snippets.
• Plots appearing in report can now be customized in a configuration file.
• Whether reference solutions are shown in plots can be configured in the report’s plot config.
• grond plot now has a --show option to display MPL plots interactively.
• Plot location_mt improved.
• ProblemConfig: added nthreads argument.
• Plot contributions: show cumulative contributions for targets providing multiple misfits.
• Optimiser can now be configured to yield exactly reproducible results by providing seed values for all random number generators involved.
• Plots sequence and fits_waveform: layout as single plot figures by default.

Fixed

• Plot descriptions and titles improved.
• Reports can now be viewed in IE.
• Improved consistency of log messages.
• Fix display issues in waveform plots (partially hidden labels).
• Various improvements on the documentation.
• Improved robustness of report generation during grund run.
