My first SDF post today, which was based on getting archive files from subversion commits, doesn't appear to be complete and in addition may have some false positives.
I have generated new lists, this time getting the archived OBSERVE.snap files from the CDS backups of userapps by the file server.
In the directory /ligo/home/david.barker/tuesdaymaintenance/24oct2025/sdf/observe there are:
mon20oct2025/ Directory of backups as of 00:39 early monday morning
wed22oct2025/ Directory of backups as of 00:39 early wednesday morning
thu23oct2025/ Directory of snaps as of 00:39 ealy thursday morning
mon-wed_diffs.txt Text file of settings changed between the monday and wednesday backups
mon-thu_diffs.txt Text file of settings changed between the monday and thursday backups
snap_diffs.bsh Shell script to generate the diffs files
snapfiles Text file of the userapps "OBSERVE.snap" files as symbolically linked from the target directories
Didn't find any other smoking guns, just the LSC-POP_A filter selection being wrong, making the anti-whitening gain wrong (see alog #87728), which we already knew about from the commit comparison Dave did previously (see alog #87718):
