Here attached a phase vs. DARM rms plot for a reference. The best squeezing observed had DIFF_RF phase slide bar tuned to 9.48 degree, CLF_RF6 phase to 0 deg,  OMC_TRANS and SPARE_D to 69.21 deg. CLF sign at input 2 is minus. The phase was optimized while looking at DARM rms area at 650Hz-750Hz.

Next is the most sqz vs. frequency plot from early afternoon (the lock stretch after 117Mpc). At high frequency we are likely limited by frequency noise (see noise budget alog47351). Not sure what's going on with bumps at 425Hz and 1852Hz. The best squeezing observed was 2.19 dB. I'd round it up and claim 2.2 dB here :) This is the first time I revisited the squeeze angle optimization since the new diode was installed and CLF power was reduced (~0.7uW CLF transmitted). The nlg during this measurement was 2.34.
