LSC / ASC Photodiode Electronics Dark Offsets Measured and Set
J. Kissel, reporting for the Commissioning Vanguard

Suspicious about problems with spurious CARM offset (see LHO aLOG 44134), and what electronics work was done today (was there really? not sure), the team re-ran the following script that measures the voltage offset on IR photo diodes in the absence of light (a.k.a the "Dark Offsets") and installs compensating digital offset in the corresponding segment / quadrant signal processing input filter bank (after first bringing the IMC to OFFLINE),
    /opt/rtcds/userapps/release/isc/h1/scripts/dark_offsets/dark_offsets.py

As such, there are ~30 new SDF values to accept in the LSC model, and ~120 in the ASC model, and ~8 OFFSETs in the IMCASC model, the SQZWFS model, and in the ISCEX and EY models.

I've accepted these all these new values into the SDF system. Attached is a screenshot for the LSC, IMCASC, SQZWFS, ISCEX, and ISCEY (I didn't screencap the acceptance of the ASC changes, apologies.)
