## Configuration file for Lassie, your friendly earthquake detector
##
## Receiver coordinates can be read from a stations file in Pyrocko format:
stations_path
:
'
stations.txt'
## Receivers can also be listed in the config file, lat/lon and carthesian
## (x/y/z) = (North/East/Down) coordinates are supported and may be combined
## (interpreted as reference + offset). Omitted values are treated as zero.
# receivers:
# - !lassie.Receiver
# codes: ['', 'ACC13', '']
# lat: 10.
# lon: 12.
# x: 2397.56
# y: 7331.94
# z: -404.1
## List of data directories. Lassie will recurse into subdirectories to find
## all contained waveform files.
