Detector was put in DOWN earlier due to very high secondary ground motion. Maintenance day is today.
Several Guardian nodes reloaded at 07:45 this morning, modifed sqzparams.py
sqzparams.py was modifed yesterday evening at 19:40 and SQZ_ANG_ADJUST was reloaded at that time to apply the code change. Five other Guardian nodes import sqzparams.py and were in CFC state this morning.
I took the opportunity to test the automatic loading of these nodes after verifying none use the modified lines in sqzparams.py. The command is
guardian_modified_not_loaded --load-nodesa confirmation is required before proceeding with the load. The nodes loaded were (pre-load params shown):
