Pursuant to LIGO-T1900555 [1] and discussions on the DetChar and HW injections mailing list [2,3], I've scheduled DetChar safety injections to begin at 23:00:00 UTC (18:00:00 CDT, 16:00:00 PDT) 3 Sep 2019. These should last for 390 seconds and contain 75 injections spaced 5 sec apart. The scheduled injections have been added to GraceDb [4]. We will update the events in GraceDb to record whether these injections were successful post-hoc. **Please note**, we have schedule coincident (but not necessarily coherent) injections at LLO for the same time. We include the LLO aLOG describing those injections in a comment below. More details on how these injections were generated and added to the HW injection SVN repo are available via a README [5].

The coincident (but not necessarily coherent) injections at LLO are described here: https://alog.ligo-la.caltech.edu/aLOG/index.php?callRep=48279I svn uploaded the waveforms and schedule file for this injection, and reloaded the guardian, so if the IFO is observing then the injections should go in.
This injection failed (see alog 51720) with what looks like the same INJ TRANS guardian error we have been seeing at LLO (see llo alog 46132 and FRS ticket 12939)
