Joe B, Darkhan T,

From the past day's lock stretches it seems that now the DARM time-dependent parameters (kappas) calculated in the CAL-CS model are mostly within expected ranges. The optical gain seems 10% lower compared to what the DARM model suggests.

Related alogs (kappas from September): 30219, 29992.

Cal. line coherence averaging:

Coherence calculations in the CAL-CS front-end model outputs overestimated coherences for the calibration lines between Sept. 20 and now. The issue will be fixed by replacing the averaging C code, BUFFER_AND_AVERAGE.c with a previous version (modification to the script proposed in LHO alog 29744 will be reverted).
