PSL 10-Day Trends

FAMIS 31135

The PSL was offline for a bit last Tuesday for chassis work that took down the interlock (alog89965), but came back up with only a few things being different. Most notably, the PMC is at a slightly different temperature, so the transmitted power is a bit lower while the reflected power is a bit higher.
