TL;DR
This paper demonstrates that joint LIGO-Virgo searches for transient signals significantly improve detection efficiency and sky localization compared to individual detector analyses, based on simulated data.
Contribution
It provides a quantitative assessment of the benefits of combined LIGO-Virgo coincidence searches for burst and inspiral signals using simulated data.
Findings
Increased detection efficiency at fixed false alarm rate
Enhanced sky localization capabilities
Significant advantages over individual detector searches
Abstract
We examine the benefits of performing a joint LIGO--Virgo search for transient signals. We do this by adding burst and inspiral signals to 24 hours of simulated detector data. We find significant advantages to performing a joint coincidence analysis, above either a LIGO only or Virgo only search. These include an increased detection efficiency, at a fixed false alarm rate, to both burst and inspiral events and an ability to reconstruct the sky location of a signal.
