After sending 6 seconds of zeroes to signal injection stream, we sent the 4 sec template signal, 12 sec of zeros, 4 sec template, 12 sec of zeros, ... The peaks were located in the center of each templates. It means that the peaks of injected signal were located on GPS0=8+16*n (n=0,1,2,...). We injected from low to high freq as below.

with tau=0.4 sec Gaussian (fixed for all templates, and its peak is located on the center of the template), template length 4 sec with 16kHz, and the Tukey window r=0.1 in order to start- and end-edges of the template are fallen down to be exactly zero. In addition, we applied the f^2 effect and normalized to be 1 at the maximum amplitude of the template waveform.
