PSL 10-Day Trends

FAMIS 31059

Late entry; these are trends taken on Monday as usual but I neglected to post them until now.

Since troubleshooting of laser glitches is still ongoing, several things in the PSL have been changing more than usual, including enclosure incursions, temperature changes, and ISS diffracted power increases. The only unexpected thing of note is that PMC reflected power seems to have been rising slowly over the past few days, but I think it's too soon to tell if this is a similar increase to what we were seeing here pre-NPRO swap or if it's related to laser troubleshooting. Will certainly be keeping an eye on this.
