Evan, Miriam,
While L1 was having a small lock loss, we made a series of injections (with H1 in comissioning mode) in the H1:SUS-ETMY_L2_DRIVEALIGN_Y2L_EXC channel. The injections are single sine-gaussian pulses that simulate blip glitches (see https://ldas-jobs.ligo-wa.caltech.edu/~miriam.cabero/sine-gaussian.png ).
We started very quiet and slowly increased the amplitude, so that only the last 3 of the 9 injections appear in GDS-CALIB_STRAIN. The GPS times of the injections are:
1174684631
1174684680
1174684715
1174684745
1174684793
1174684854
1174684889 *
1174684945 *
1174685355 *
* Can be seen in CALIB_STRAIN
We will be repeating this kind of injections at opportunistic times (L1 not observing) in the next days, taking different blip morphologies, and different amplitudes.
