Now that all the CDS overview lights are green, I decided to switch back the coil driver outputs to their original state so that the MC optics could be damped and the IMC relocked. I also restored the static PIT/YAW bias values to their original values.

MC1 has been quiet over the last couple of days, lets see how it behaves in the next few days. In all the glitches I have observed, if the IMC is locked and WFS loops are enabled, the loops are able to correct for the DC misalignment caused by the glitch. But the mcwfs off script is currently set up in such a way that the output history is cleared between IMC locks. I made two copies of the mcwfson/mcwfsoff scripts, called mcwfsunhold/mcwfshold respectively. They live in /opt/rtcds/caltech/c1/scripts/MC/WFS. I've also modified the autolocker script to call these modified scripts, such that when the IMC loses lock, the WFS servo outputs are held, while the input is turned off. The hope is that in this configuration, the autolocker can catch a lock even if there is a glitch on MC1.

I haven't tried locking the arms yet, but I think other IFO work discussed at the meeting (like arm loss estimation / cavity scans etc) can proceed.
