Craig, Georgia

We were struggling to increase power all afternoon today.  Georgia and I measured the IMC and CARM OLGs at 2W, and moved the gain sliders a bit to check if they were doing what they should be.  They are.  (Attachment one)

IMC Nominal UGF = 51 kHz
IMC -3 dB on IMC FASTGAIN UGF = 35 kHz
IMC +3 dB on IMC FASTGAIN UGF = 77 kHz

CARM (first) Nominal UGF = 25 kHz
CARM -3 dB on LSC IN1GAIN UGF = 14 kHz

The IMC OLG isn't moving too much on power-up (attach two), but it is down from where it was in November (IMC UGF Nov 2018 = 73 kHz). The CARM OLG is known to fall to around 10 kHz.
There is no problem with the CARM UGF falling below the IMC UGF during power-up, or with the gain slider redistribution, especially since we have powered-up just now.
