4.6.1.1.2. eqcorrscan.core.bright_lights.coherence

eqcorrscan.core.bright_lights.coherence(stream_in, stations=[‘all’], clip=False)[source]

Determine the average network coherence of a given template or detection.

You will want your stream to contain only signal as noise will reduce the coherence (assuming it is incoherent random noise).

Parameters:
  • stream_in (obspy.core.stream.Stream) – The stream of seismic data you want to calculate the coherence for.
  • stations (list) – List of stations to use for coherence, default is all
  • clip (tuple) – Default is to use all the data given (False) - tuple of start and end in seconds from start of trace
Returns:

tuple of coherence and number of channels used.

Return type:

tuple
