PSL 10-Day Trends

FAMIS 63909

Ignoring the past couple of hours when the laser went down due to interlock work and Jason and I went into the enclosure (alog91287), things are looking pretty good. The FSS RefCav transmission is drifting down and has generally been lower than we've seen it, so at some point before IR01 we'll go in and realign the FSS path. Next week I'll compare things after the PSL is recovered in the next couple of days.
