eqcorrscan.core.template_gen.multi_template_gen

eqcorrscan.core.template_gen.multi_template_gen(catalog, st, length, swin='all', prepick=0.05, all_horiz=False, delayed=True, plot=False, debug=0)[source]

Generate multiple templates from one stream of data.

Thin wrapper around _template_gen to generate multiple templates from one stream of continuous data.

Parameters:
  • catalog (obspy.core.event.Catalog) Events to extract templates for
  • st (obspy.core.stream.Stream) Processed stream to extract from, e.g. filtered and re-sampled to what you want using pre_processing.dayproc.
  • length (float) Length of template in seconds
  • swin (string) P, S or all, defaults to all
  • prepick (float) Length in seconds to extract before the pick time default is 0.05 seconds
  • all_horiz (bool) To use both horizontal channels even if there is only a pick on one of them. Defaults to False.
  • delayed (bool) If True, each channel will begin relative to it’s own pick-time, if set to False, each channel will begin at the same time.
  • plot (bool) To plot the template or not, default is True
  • debug (int) Debug output level from 0-5.
Returns:

list of obspy.core.stream.Stream newly cut templates

Return type:

list

Note

By convention templates are generated with P-phases on the vertical channel and S-phases on the horizontal channels, normal seismograph naming conventions are assumed, where Z denotes vertical and N, E, R, T, 1 and 2 denote horizontal channels, either oriented or not. To this end we will only use Z channels if they have a P-pick, and will use one or other horizontal channels only if there is an S-pick on it.

Warning

If there is no phase_hint included in picks, and swin=all, all channels with picks will be used.
