Coherent Burst Hardware Injections

I've scheduled 9 burst injections to be injected coherently into both IFOs. They will begin at 10:10 UTC (2:10 PT) and are spaced 20 minutes apart. The IFO will need to be in observation mode for these injections to go in. Here are the relevant lines in the schedule file.

The waveforms are on the hardware injection svn. The schedule file gives the path to the text files from the Details directory.

If for some reason these injections need to be stopped, follow these instructions:

  1. On a workspace, open a terminal.
  2. Type 'guardmedm INJ_TRANS', this will open the gui for the transient injection guardian.
  3. From the request pull down menu, select INJECT_KILL

Here is a link to the Burst groups ER10/O2 hardware injection plans - https://dcc.ligo.org/LIGO-G1601528

In the schedule file - ADI = Acretion Disk Instability, SG = Sine Gaussian.

At LHO, the first injection that went in was the 6th scheduled injection (ADI-e_20_0.9.txt). Unfortunately this was the only injection that went in at LHO, and the only one that was coherently injected at both sites. The remaining three injections were stopped by the guardian because there was an external trigger alert, which I'm guessing was due to the injection itself.

I've attached the relevant section of the INJ_TRANS guardian log.
