Earth azimuth effect in the bank of search templates for an all sky search of the continuous gravitational wave
Abstract
We study the problem of all sky search in reference to continuous gravitational wave (CGW) whose wave-form are known in advance. We employ the concept of Fitting Factor and study the variation in the bank of search templates with different Earth azimuth at t=0. We found that the number of search templates varies significantly. Hence, accordingly, the computational demand for the search may be reduced up to two orders by time shifting the data.
