corr_cluster
(trace_list, thresh=0.9)[source]¶ Group traces based on correlations above threshold with the stack.
Will run twice, once with a lower threshold, then again with your threshold to remove large outliers.
Parameters: - trace_list (list of obspy.Trace) Traces to compute similarity between
- thresh (float) Correlation threshold between -1-1
Returns: np.ndarray of bool
Note
We recommend that you align the data before computing the clustering, e.g., the P-arrival on all templates for the same channel should appear at the same time in the trace. See the stacking.align_traces function for a way to do this
