Performance of an externally triggered gravitational-wave burst search

We present the performance of searches for gravitational-wave bursts associated with external astrophysical triggers as a function of the search sky region. We discuss both the case of Gaussian noise and real noise of gravitational wave detectors for arbitrary detector networks. We demonstrate the ability to reach Gaussian limited sensitivity in real non-Gaussian data, and show the conditions required to attain it. We find that a single sky position search is $\ensuremath{\sim}20%$ more sensitive than an all-sky search of the same data.
