Zusammenfassung:
χ2 vetoes are commonly used in searching for gravitational waves, in particular for broadband signals, but they can also be applied to narrowband continuous wave signals, such as those expected from rapidly rotating neutron stars. In this paper, we present a χ2 veto adapted to the Hough transform searches for continuous gravitational wave signals; we characterize the χ2 significance plane for different frequency bands and discuss the expected performance of this veto in LIGO analysis.
