Commencing relocking post-maintenance day
I was struggling to get past SRC_ALIGN during initial alignment after maintenance day. Sheila noticed that the offset of H1:LSC-POP_A_LF_OUT_DQ had changed for some reason during the course of maintenance day. She took an average of the offset value and updated it in the filter module. This will inevitably cause an SDF diff that will need to be accepted before going to Observe.
Don't forget that all the models on h1lsc0 had to be restarted this morning due to a timing glitch.
