A few EPICs channels added to top-level CAL-CS Front-end model
J. Kissel, L. Dartez ECR E2400103 IIET 30760 WP 11786 To better coordinate and confirm the front end portion of the calibration pipeline and the GDS portion running on the DMT machines remain in sync in terms of calibration model installed, which is necessary for good calibration, we are adding two slow 16 Hz EPICS channels to the h1/l1calcs models (so both LLO and LHO) that will be added to the GDS broadcaster list so the GDS calibration pipeline can read them. These are H1/L1:CAL-CALIB_REPORT_ID_INT and H1/L1:CAL-CALIB_REPORT_HASH_INT. Louis and I created the top-level EPICs records today; see attached screenshot. The change has been committed to the userapps SVN under: /opt/rtcds/userapps/release/cal/h1/models/ h1calcs.mdl committed at rev 27307. It's in no way a complicated add to the model, but I've ran a test compile of the h1calcs.mdl on the build machine anyways just to check. The test compiled succeeded without issue.

J. Kissel This model changes have been installed this morning. As such, I've updated the safe.snap SDF system to initialize the H1:CAL-CALIB_REPORT_ID_INT and H1:CAL-CALIB_REPORT_HASH_INT channels. I've also chosen to monitor them, since we don't expect them to change during observation, and/or regulary, and this information will become critical for calibration librarianship.
