Analysis Results
Note: These p-values measure the consistency of the observed track-like events with the known atmospheric backgrounds for this single map (not trials corrected for multiple GW events).
The most probable direction is the maximum probability RA, decl. found in the generic transient search (reported when the p-value for that search is less than 10%).

Coincident Events
- dt = Time offset (sec) of track event with respect to GW event merger time (t_nu - t_merger).
- RA (J2000) (deg) = Right ascension of the event (in degrees).
- Dec (J2000) (deg) = Declination of the event (in degrees)
- Angular unc = Angular uncertainty of track event: the radius of a circle representing 90% CL containment by area.
- Event p-value (generic transient) = the pvalue for this specific track event with respect to a background only hypothesis in the generic transient search
- Event p-value (Bayesian) = the pvalue for this specific track event with respect to a background only hypothesis in the Bayesian search
Note: if this is a Significant LVK event, a skymap zoomed in around the most probable direction will be included below this table.
