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.12 Pages, 3 figuresAstrophysicstext
