While recovering from a quick earthquake, I took opportunity to tweak the ALS x&y fiber polarizations (see attached).

• ALSx at:  33  (it was also listed as too large via DIAG_MAIN)
• ALSy at:  18

Powering on the remote control immediately shoots both values to a high value, and then after that I started the usual adjustments. 

• For X, could only get down to  ~21 (which is normal for O3), and
• For Y, could only get down to ~5 (which is not normal, usually we can get close to 0).

Adjustment session #2 (power remote control OFF, and then ON.  This time I had:

• X:  ~19 (with it waivering up to 21)
• Y:  ~0 (much better)

Not sure what going through the procedure twice did (and whether it was worth it).  Moving on!
