3 earthquakes, 2 user errors and 1 PI gave us the opportunity to extensively test our lock acquisition sequence today. 

(It works pretty well actually. The weakest part is the DRMI lock: the interferometer ends up always misaligned right after an unlock, and it requires manual adjustments all the times to get DRMI to lock. Once the DRMI locks, than the locking sequence rarely fails.)

Today we explored the (allegedly) jitter/intensity noise as function of interferometer alignment (SRM alignment, CSOFT/DSOFT and PRC1 offsets).

More details will follow, but the bottom line is that we have been able to increase the recycling gain (max 31, typically 28-29, with PRC1_Y offset= -0.06, CSOFT_P = +0.120), the cavity pole (360, typically 340), and minimize "jitter", but we have not been able to do everything at the same time.

All the noise tuning steps (including the now standard CO2X 240 mW power) are in the guardian, except the IMC WFS offsets. We also run  A2L.

We leave the interferometer locked with the SRM aligned by hand to minimizes jitter noise (ASC still open), with recycling gain 29 and cavity pole ~340 (as measured by CAL_CS_TDEP_F_C channel). The range is approaching 70 Mpc.
