KAGRA Logbook

Attached is a plot of the in-lock signals of the PMC. All signals are cast into ADC counts of the MIXER_MON to mach their signals (stay tuned for calibration in meters).

To match the data traces I had to add a pole at 1Hz for FAST_OUT1, and poles at 1Hz and 60Hz, and a zero at 10Hz for PZT_HV_MON. I am a little puzzled with the exact values of those roll-offs.

Either way, we need some whitening for MIXER_MON and FAST_MON. Luckily the Daughter board has provisions for those filters, so we can add them next week.
