At 11:55 (04:55) IFO dropped out of Observing due to SDF Difss with CALINJ SDF Diffs. At 12:01 (05:01) Accepted SDF Diffs and put IFO back into Observing Mode.
It may be unrelated but lostlock at 12:04 (05:04).

It would be better to un-monitor these channels in the SDF as they change when we carry out hardware injections. The injections should have finished at 5:01:30 PDT, which doesn't quite match up with the lockloss at 5:04.

These injections do not appear to have been successful in as much as H1:DMT-INJECTION_DETCHAR:1 was not active during any of the injection times. We're re-scheduling these for the morning of Fri March 29, 2019.

To un-monitor the channels open the SDF screen for CAL-INJ (while in Observe), set the "TABLE SELECTION" to "FULL TABLE", set "MONITOR SELECT" to "ALL" (this part may not me necessary). Channels with the final green tab lit up are currently being monitored. To un-monitor a channel click on the "MON" tab and hit the "CONFIRM" button. A list of the channels that we want the monitoring removed are shown in this screenshot (the ones with the yellow box in front of MON).
The schedule file and waveforms have been uploaded to the h1hwinj1 machine and I asked Gary (at LLO) to ask Patrick to reload the INJ TRANS guardian.
