To help with troubleshooting H1 locking, I have compiled a list of Guardian code changes which have been made since the last robust locking on Monday 20th October 2025.
30 nodes have been reloaded with modifed code since Monday. Note that some of these reloads were to just resync the nodes to the latest lscparams.py and clear the GRD-CFC.
A summary of the nodes is given in the attached txt file.
Full details of the code changes can be found in /ligo/home/david.barker/tuesdaymaintenance/23oct2025/grd_diffs/
Filter Module changes since Monday.
the following models have had filter module changes since Monday:
h1sus[mc1, mc2, mc3, pr3, sr3]
h1isietm[x, y]
h1asc
