I have turned the PSL OFF, and it will remain in that state for the duration of the holiday break.  I have also turned OFF the PMC, FSS, and ISS inner loop.  In addition to this, at Peter's suggestion, I have also switched OFF the transimpedence chassis for the ISS second loop.  The chillers have been left ON so that there is no standing water in the cooling lines of the laser.  The PSL will be turned back ON on the morning of January 3rd, 2018.  I hope everyone has a Happy Holiday!
