Sheila said to watch time series of (4) ALS Channels for glitches. They are:
H1:ALS-X-REFL_CTRL_OUT_DQ
H1:ALS-Y-REFL_CTRL_OUT_DQ
H1:ALS-C_TRX_A_LF_OUT_DQ
H1:ALS-C_TRY_A_LF_OUT_DQ
Have noticed some drops on these channels corresponding with locklosses while locking.
Sheila mentioned that previously this effect would go away on its own, so there may be hope. Or, if the effect becomes more infrequent, if one can zip through the locking sequence and get to atleast RF_DARM, then one could be "home free". (So far, the glitches have been taking H1 down at most steps starting at LOCKING_ARMS_GREEN up to PREP_TR_CARM.
I just finished an Initial_Alignment, and am now trying to see if we can get past RF_DARM and elude the dreaded ALS glitches. (So far I am 0for5 in the last 20minutes of locking.)
