H1 DMT Calibration Bit Will Remain Bad For the Evening
J. Kissel

I've completed analysis of the new 2017-01-03 reference measurements (LHO aLOG 32942) that were taken after the L2/L3 cross-over upgrade (see LHO aLOG 32933), and including the updates to the AA/AI filtering (see LHO aLOG 32907). I will post more details later.

However, I have not yet pushed these results to DARM loop model parameters or the front end replica, nor have I generated new EPICs records to go with them. Therefore, the time-dependent correction factors, which use the update EPICs records will still be ~15-30% incorrect as they've been since the L2/L3 crossover change (i.e. the entire datset since the restart after the break), and will flag the calibration as bad, which means the ANALYSIS_READY bit will still be flagged as bad the up-coming lock stretches over night.

My hope is to get better information out within 24 hours.

Apologies, and thank you for your continued patience.
