How many templates for GW chirp detection? The minimal-match issue revisited

摘要

Refined estimates for the template density (or minimal match) yielding the best trade-off between a detector's performance (in terms of false dismissals) and computational burden are obtained in the context of the maximum likelihood of detection of gravitational wave chirps from coalescing binaries with unknown parameters, using a recently derived accurate representation of the no-signal cumulative distribution of the detection statistic.
