Over the lock period last night, the CPS ASD appears to experience changes as time passes.

Just to focus on the BS, the ST2 Vertical between 1 and 5 hz see the largest variation.  See the two attached images, the lower right panel is the ST2 Vertical.  The lighter thicker colors are references before the CPS timing change on Tuesday.  The finer darker traces are current running.  I've look at the ITMY & ITMX too over the few hours of the lock loast night, and at some time or another, all the traces are at or below the reference, suggesting the CPS are okay.
