Abstract : In a search for gravitational waves from compact binary coalescences using a network of detectors, the data are analyzed separately for each detector, to generate 'single-detector triggers'. A coincidence test is then performed on the reported triggers that checks the consistency of the signal parameters (such as the masses of the compact objects and the time of arrival of the signal) estimated from multiple detectors. We propose a coincidence test based on normal difference distribution of trigger parameters and calculating false dismissal probability for each set of triggers. We can choose to reject triggers for which false dismissal probability is below a certain threshold value. This formulation enables us to fold in the prior distribution of the sky location of compact binaries that is detectable by a detector network.
