PyPI version Documentation Status Build Status Coverage Status

Quickstart for python

To discover trigger files for a given channel:

>>> from gwtrigfind import find_trigger_files
>>> cache = find_trigger_files(channel, etg, gpsstart, gpsend)

The resulting cache can then be read easily into a table using gwpy:

>>> from gwpy.table import EventTable
>>> t =, format='ligolw', tablename='sngl_burst')

The format argument depends on the etg you use, but is likely to be one of 'hdf5', 'ligolw', or 'root'.

Quickstart for command-line

The same query can be performed from the command line by passing each of the functional arguments above as arguments to the gwtrigfind executable script:

gwtrigfind <channel> <etg> <gpsstart> <gpsend>
