**RAVEN** [#RAVEN]_ In addition, we will operate the Rapid On-Source VOEvent
Coincidence Monitor (RAVEN), a fast search for coincidences between GW online
pipeline events and gamma-ray bursts or galactic supernova notifications.
Coincidence Monitor (RAVEN), a fast search for coincidences between GW and non-GW
events external to the LIGO collaboration. RAVEN will process alerts for
gamma-ray bursts (GRBs) from both the *Fermi*-GBM instrument and the Neil
Gehrels Swift Observatory, as well as galactic supernova alerts from the
SNEWS collaboration. Two astronomical events are considered coincident if they
are within a particular time window of each other, which varies depending on
which two types of events are being considered (see the table below). Note
that these time windows are centered on the GW, e.g., [-1,5] s means we
consider GRBs up to one second before or up to 5 seconds after the GW.

In addition, RAVEN will calculate coincident false alarm rates, one including
only timing information (temporal) and one including GRB/GW sky map
information (space-time) as well. RAVEN is currently under review
and is planned to be able to trigger preliminary alerts once this is finished.
