5.14.1.2. eqcorrscan.utils.seismo_logs.flag_time_err

eqcorrscan.utils.seismo_logs.flag_time_err(phase_err, time_thresh=0.02)[source]

Find large time errors in list.

Scan through a list of tuples of time stamps and phase errors and return a list of time stamps with timing errors above a threshold.

Note

This becomes important for networks cross-correlations, where if timing information is uncertain at one site, the relative arrival time (lag) will be incorrect, which will degrade the cross-correlation sum.

Parameters:
  • phase_err (list) – List of Tuple of float, datetime.datetime
  • time_thresh (float) – Threshold to declare a timing error for
Returns:

List of datetime.datetime when timing is questionable.
