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.
