Relocked without any issues, just the usual tweaking of ETMs to get ALS to lock.  Sudarshan called about the lockloss and said that likely the PCal X HF line would be reverted to a 1501.3 Hz due to the lockloss, and asked me to change it back to 2001.3 Hz when at NLN.  I did so. 

SDF diffs accepted in order to go to Observe (see screenshots).  These are the same SDF diffs, but inverted, that Ed accepted at the last lockloss (see aLog 38009).  Should these become unmonitored, or is something else bad going on here??
