Range drop during this lock

Our range hasn't been the most stable during this lock. There's one drop in particular that goes down about 8Mpc to 145Mpc for 20min or so (attachment 1). Running our range comparison script, and changing the span appropriately (thanks Oli!), it looks to be a very broadband from ~40-200Hz. The SQZ BLRMS see something around that time (attachment 2).

Sheila had me run another template for that time. The template, which was copied from one of Camilla's, I've now saved in the sqz userapps - attachment 3. Green being the trace from this lock.
