detection_multiplot about eqcorrscan HOT 3 CLOSED

This is because I haven't tried using templates that long, so the x-axis is labelled to seconds, I can rotate the axis labels - I'll have a play later.

I am curious as to why you are using such long templates? Do you think there is useful information in all of the coda?

You could certainly offset the template vertically by adding some constant to the template data, I can add this as an option.

Hmm that is a good point, I could certainly reduce the amount of noise detected by clipping off the coda. The long templates were originally chosen because some of the intermediate depth earthquakes were quite far from the stations so the actual waveforms were quite long, with a large gap between P and S arrival.
But it might be a better idea to match the vertical components to the a window around the P arrival and the horizontal components to a window around the S arrival and give some leeway for the earthquake distance/depth.

That (using P on the vertical and S on the horizontal) is what I usually do, and it looks like what you have done in the figure. Generally you get higher correlation values with shorter waveforms as there is less noise...
EQcorrscan.core.match_filter takes care of all (hopefully) the lagging and alignment problems that could come from having large and very variable source - receiver distances.
As an aside, I don't usually use templates longer than 6s. For local micro-earthquakes with impulsive arrivals I would usually use shorter, 1-3s templates. Plans are afoot to conduct a detailed study into how template variations affect the detections, but that will be a long time away.
