Memo of Hardware Injection (Sine-gaussian waveforms)
* Since Apr. 23, 2020. 03:07:18 AM, JST
* Notation: Start timing, EXC-channel, Comment
X-PCAL: 1271614656 (03:07:18 JST), K1:CAL-PCAL_EX_0_INJ_V_EXC
DARM2: 1271615520 (03:31:42 JST), K1:LSC-DARM2_EXC
ETMX: 1271616384 (03:46:06 JST), K1:VIS-ETMX_TM_SUMOUT_L_EXC
ETMY (1st injection): 1271617248 (04:00:30 JST), K1:VIS-ETMY_TM_SUMOUT_L_EXC, Stopped just after starting because of the lockloss.
ETMY (2nd injection): 1271617856 (04:10:38 JST), K1:VIS-ETMY_TM_SUMOUT_L_EXC
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.
