FAMIS 31055

The PSL has been taken down a few times in the past week as part of the glitching investigations, and this is seen clearly on several trends. Also, since the NPRO controller was swapped 5 days ago but the potentiometers on the daughter board were not adjusted on the one swapped in (alog80566), some of the readbacks for the NPRO channels are reporting inaccurate values, namely the laser diode powers. The controller is planned to be swapped back to the original tomorrow so these readbacks will be fixed.

Other item of note is that every time the PMC was unlocked last week, it seems to have relocked with a slightly higher reflected power and corresponding lower transmitted power (see stabilization trends). Looking at the PMC REFL camera image, there could be something to gain from an alignment tweak into the PMC, so I'll try that tomorrow during maintenance and see if there's any improvement.
