The ArcLinkByEvent module reads parts of seismic waveforms from continuous data based on the timing of the seismic event. It uses the ArcLink module and does not work without it. The time and length of the waveforms are determined based on the event time or the times of the seismic phases and the times before and after the event defined in the configuration file. After loading the records, it does not delete the existing event elaboration.
The list of channels to read is set in the Arclink module.
The module provides two functionalities: Get waveform by event time and Get waveform by picks time. The Get waveform by event time function loads the time segment of the seismogram taking into account the time of the earthquake. This action is called with File
ArcLinkGet waveform by event time command. Whereas the Get waveform by pick time function loads a time segment taking into account the times of the seismic phases for the station. This action is called with the command FileArcLinkGet waveform by pick time.
Reading from ArcLink seismic recordings based on the earthquake data is one of the most commonly used commands for automatic event processing during working on multiple events.
