ESD Calibration Lines Truned Back ON
J. Kissel, S. Ballmer

The ESD / DARM calibration lines have been OFF since the CAL-CS front-end model changes this past Thursday (LHO aLOG 19875), because the channel names that generate them have changed. I've used LHO aLOG 19792 to restart them with the newly high SNR.

As Stefan mentions in LHO aLOG 19925, I turned this back on just before the current lock stretch's undisturbed bit was engaged.

For the record, the new channels are
H1:CAL-CS_TDEP_ESD_LINE1_DEMOD_OSC_FREQ       34.7 [Hz] 
H1:CAL-CS_TDEP_ESD_LINE1_DEMOD_OSC_CLKGAIN    0.22 [ct]

H1:CAL-CS_TDEP_ESD_LINE2_DEMOD_OSC_FREQ       538.1 [Hz]
H1:CAL-CS_TDEP_ESD_LINE2_DEMOD_OSC_CLKGAIN    2.4 [ct]
I've overwritten the current EPICs database to the SDF safe.snap, and loaded in the new table to initialize all of the newly named channels. A large fraction of them are now not monitored (417 out of 1188), but I've at least gone through the ESD LINE CLKGAIN and FREQs to make sure they're monitored. I would monitor more, but I don't want to sort on substring (see LHO aLOG 19650).
