v1.1.0

This is a minor version upgrade that contains only documentation updates, minor changes and bug fixes

ENHANCEMENTS:

• Documentation
• eval-xcorr command line option output has improved (see documentation)
• source origin id is now stored in the relocated origin as comment (scrtddSourceOrigin)
• Signal to Noise ration option has improved

BUG FIXES:

• -O and --ep options do not work together but they are supposed to
• theoreticalPhaseManualOrigin option doesn't create automatic picks for all manual origins in a catalog

CONFIGURATION CHANGES:

• removed scrtdd.publicIDpatter: scrtdd uses global.publicIDpattern instead
• many default parameter values have been updated with more sensible values

v1.0.0

This is pretty much the same as "v1.0.0 Release Candidate 4" but the documentation of some configuration options have been updated and a bug in --merge-catalog command line option has been fixed

v1.0.0 Release Candidate 4

BUG FIX: fixed computation of partial derivatives in the solver that were slightly incorrect

ENHANCEMENTS:

• improvement to --evel-xcorr option
• processing logs are now saved to in the working directory

v1.0.0 Release Candidate 3

BUG FIX: the relocated phase file (relocated-phase.csv) generated by the multi-event relocation cannot be properly read back into scrtdd

v1.0.0 Release Candidate 2

NOTABLE CHANGES:

• multi-event relocation is now performed per cluster: instead of relocating all events in one single double-difference system each cluster is relocated independently. This results in improved solutions since the parameters of the solver are cluster dependent (e.g. downweighting by residuals). Also each cluster covers a smaller area, which helps in avoiding breaking the solver assumption of a flat earth surface (the lat/lon/depth coordinates are converted internally to an euclidean geometry system by the solver)

ENHANCEMENTS:

• changed default configuration values: damping factor enabled by default, meanShiftconstraintWeight disabled. Although those parameters influence each other, the main advantage of damping factor is that it is able to constrain mean shift of the events even when relocating multiple clusters, while meanShiftconstraintWeight works better only when relocating a single cluster
• solver now logs residuals by inter-event distance: this is useful to understand how the relocation is going since the residuals should increase with inter-event distance if the events are correctly relocated (see Waldhauser/Ellsworth)

v1.0.0 Release Candidate

NOTABLE CHANGES:

• A new double-difference system solver has been added to the module and the external HypoDD software is no more required. Users who want to keep using the HypoDD software as a solver need to stick to the former v0.99.x release series but keep in mind that is not going to be maintained anymore

WARNING:

• The module configuration has changes. A new configuration has to be created for this new version

ENHANCEMENTS:

• Added --eval-xcorr command line option to evalutate the configuration of the cross-correlation settings. See documentation for more details
• The clustering algorithm is much faster
• The clustering algorithm selects now only well-connected events (minimum number of observations and neighbours must match all involved peers in a cluster)
• better waveforms caching mechanism

BUGS:

• Neighbouring selection by ellipsoid algorithm selects wrong candidates sometimes

v0.99.4

WARNING:

• The catalog format has changes. Catalog files generated with previous versions are no longer valid

BUGS:

• since HypoDD supports station ids with a maximum length of 7 chars, sometimes the realocation fails due to the station ids generated by scrtdd being too long. Now the station ids are converted before being used to create HypoDD input files

ENHANCEMENTS:

• scrtdd is not able to deal with multiple location codes for the same stations. In previous releases errors were produced when a station had more than one location codes.

v0.99.3

BUGS:

• filtering phase by station distance doesn't work properly during clustering

PERFORMANCE:

• fixed a regression introduced in release v0.99.1: the waveforms are downloaded multiple times from the configured RecordStream, which result in a increased relocation time
• -O and -ev options: when relocating an origin from command line do not try to preload the entire catalog into memory, it is useless and the user has to wait for that to finish

CHANGES and ENHANCEMENTS:

• Automatict phase pick times coming from the catalog are never updated with the results of cross-correlation (this still happens in real-time relocation to the origin phases of the event is going to be relocated)
• when trying to match the channels of two phases (e.g. HH-HH or HG-HG) during cross-correlation always try to match the real-time origin phase channels with the catalog ones

v0.99.2

CHANGES and ENHANCEMENTS:

• added command line option --debug-wf-cache: normally only catalog phases are cached, since they are going to be re-used. With this option all waveforms are cached, also temporarily ones (e.g. theoretical phases) and makes debugging much faster. After the debug is finished, the cache folder should be deleted
• Automatic and theoretical phases without a good SNR are dropped from the relocated origin: This is done only after the pick time has been fixed using cross-correlation results
• improved responsiveness of scrtdd relocator within scolv: check that scrtdd is running before waiting for a relcoation message
• cross-correlation logs improvements: when logging the results of cross-correlation sort results by station distance. Also log the average lag among all cross-correlation pairs.

v0.99.1

Minor improvements over the previous release
