Abstract
In this paper we explore the differences of results of GW searches with the gstlal pipeline/method applied to real LIGO data and simulated colored-gaussian data.
This difference is quantified with a statistical likeliohood test, and is used to find out significant differences depending on bank parameters such as chirp mass, symmetric mass ratio, tau0, and tau3.
We find that regions in the template bank representative of very high mass present a significantly less gaussian behaviour than those of low mass up to a point, after which the very low mass regions start presenting an unexpected non-gaussian behaviour equivalent to very high mass regions.
