Just before we went into Observing, I (finally) ran the cbc hardware injections that are necessary for the final NonSENS review sign-off.  LLO ran these injections during O4a (LLO alog 69132), but I ran out of time before the commissioning break.  While the IFO is improved since the end of O4a, the cleaning parameters that are in place during the time of that test are all the same as were present for the last several months of O4a. In particular, both jitter cleaning and laser noise cleaning were turned on during this test (even though later I turned off laser noise cleaning for O4b, see alog 77069).

injection start GPS: 1396738718.28

Below is the output of the terminal during this test, which ran for about 93 seconds.
