autosigma

Strong event parameter processing

Description

AUTOSIGMA is an automatic module to compute and visualize ground motion parameters based on SeisComP events. The computed parameters are stored as incidents in the SIGMA database.

Module Configuration

~/.seiscomp/autosigma.cfg

autosigma inherits global options.

Note

Modules/plugins may require a license file. The default path to license files is @DATADIR@/licenses/ which can be overridden by global configuration of the parameter gempa.licensePath. Example:

gempa.licensePath = @CONFIGDIR@/licenses

magnitudeFilterTable

Type: list:string

Magnitude-dependent filter table. The format is "mag1:fmin1;fmax1, mag2:fmin2;fmax2, mag3:fmin3;fmax3". If a magnitude falls between two configured magnitudes, the filter of the lower magnitude is used. No interpolation takes place. Magnitude outside the configured range are clipped to the lowest/highest value. Frequency values are given as simple positive doubles (Hz is assumed) or with suffix "fNyquist" which is then multiplied by the Nyquist frequency of the data to get the final corner frequency.

The final frequency values are used as a replacement for the profile filter.loFreq and filter.hiFreq parameters unless the table is empty.

profiles

Type: list:string

A list of profiles defining event and region criteria with processing. Provide at least one profile.

Note

cron.* Timing parameters controlling the automatic event processing.

cron.wakeupInterval

Default: 10

Unit: s

Type: int

Time interval to test for new events.

cron.eventKeep

Default: 3600

Unit: s

Type: int

The time interval to keep events in the buffer. During this interval events are available for processing.

cron.delayTimes

Unit: s

Type: list:int

List of time intervals to delay the processing of new events. The delayTimes are added to the originTime. delayTimes > 0 s allow to load complete waveforms within the requested time windows. Provide a comma-separated list to repeat the data processing of new events allowing for more complete data from stations with longer data delay or larger epicentral distances.

cron.updateDelay

Default: 60

Unit: s

Type: int

Time delay to test for event updates of already loaded events.

Note

acquisition.* Control parameters for waveform data acquisition.

mag1:km1, mag2:km2, mag3:km

The distance value is given in km. If a magnitude falls between two configured magnitudes, the distance of the lower magnitude is used then. No interpolation is performed. Magnitude outside the configured range are clipped to the lowest/highest value.

The final value is used as a replacement for acquisition.maximumEpicentralDistance unless the table is empty. Example: 3:400, 4:450, 5:500

Unit: s

Type: int
