Correlation-derived seismic phase arrival times from matched-filter studies of Yellowstone (Wyoming) 2017, Kilauea volcano (Hawaii) 2018, and Ridgecrest (California) 2019: A dataset for developing phase-picking neural networks

This dataset contains correlation-derived seismic phase arrival times from three different studies:

One comma separated value (CSV) file is uploaded for each sequence.  Each file contains the following fields:
 
template_id:  The assigned ID for the template
 
match_id: the assigned ID for the detected event
 
network: The network code for the seismic station
 
station: The name of the seismic station
 
phase: Seismic phase, P or S
 
arrival: The arrival time, calculated based on the template phase pick time and the correlation-derived differential time, given in epoch time (seconds since January 1, 1970, UTC)
 
weight: The weighting assigned in the original study, (0.1 +3ccdiff)ccmax2 (see explanations of ccdiff and ccmax below)
 
mag: The magnitude determined for the detected event (see original study for details)
 
ccmax: The peak cross-correlation coefficient (the largest absolute value correlation coefficient, including its sign)
 
ccdiff: The difference between the absolute value of ccmax and the second largest absolute value correlation peak
 
chanloc: The seismic channel and location codes, separated by “.”
