We scheduled coherent hardware injections using the updated tinj that uses PINJX_TRANSIENT_EXC to inject signals. Previous aLog H1 entries are aLog 23346 and aLog 23352.

There was one injection performed at H1 and L1. The end time of the injection is 1131397646.4185 and the gracedb event is: H200134 (has links to waveform file and parameters)

For this successful injection the intent bit at LLO turned off when awgstream was envoked but at LHO the intent bit remained on. Adam updated DIAG_EXC to exclude l1calex from knocking the interferometer out of observing mode if there is an excitation.

Two other injections were canceled because of this problem.  The canceled injections used the same waveform and had end times of:
1131398726.42
1131399806.42

After DIAG_EXC was updated Adam and I tried another injection. The end time was: 1131405166.42

We cancelled the injection because we had a gracedb alert. awgstream had already been called when we were alerted. So the last injection at 1131405166.42 was cancelled by stopping run_tinj with the monit web interface and then killing the awgstream process that was running under the hinj account. I restarted run_tinj after the awgstream process was killed.
