For the Record: SRM Damping Loop EPICs Gains have been set at -0.5 since Apr 21 2023
J. Kissel

Just stating for the record, as the 2023 aLOG records are a bit unclear (LHO:72106 and LHO:72130 are all I could find, and they claim -0.2), I state here that all DOFs of H1 SUS SRM's M1 damping loop gains have been at -0.5 since 2023-04-21 22:49 UTC, prior to that, they were the -1.0 as designed (see 2022 upgrade to "level 2.0", LHO:65310). See attached trend confirming this to be true.
