# 5.7.1.1. eqcorrscan.utils.findpeaks.coin_trig

`eqcorrscan.utils.findpeaks.``coin_trig`(peaks, stachans, samp_rate, moveout, min_trig, trig_int)

  Find network coincidence triggers within peaks of detection statistics.

  Useful for finding network detections from sets of detections on individual stations.

  Parameters: | peaks (list) List of lists of tuples of (peak, index) for each station-channel. Index should be in samples. stachans (list) List of tuples of (station, channel) in the order of peaks. samp_rate (float) Sampling rate in Hz moveout (float) Allowable network moveout in seconds. min_trig (int) Minimum station-channels required to declare a trigger. trig_int (float) Minimum allowable time between network triggers in seconds.
  Returns: | List of tuples of (peak, index), for the earliest detected station.
  Return type: | list
