Matt over heard me talking to Yuki about PCAL actuation and asked the time-honored question of whether the current "large" calibration lines were causing any non-linear impact in the DARM sensitivity. I've not proved this suspicion wrong in a few months, and not after starting the huge 7.9 Hz SRC detuning tracker line, so I figured I'd oblige. 

As such, I've turned off the PCALY lines during this lock stretch at 05:51:42 UTC, and restored them at 06:11:00 UTC.
(Note, for those who are looking behind me, we were running A2L for the majority of the time between reaching nominal low noise and starting this test. Commissioning also broke the lock just after the test.)

The current line amplitudes do not adversely affect the DARM sensitivity in any other way than expected. Also for the record BNS range was identical between ON vs OFF as well.
