Beginning Measurement Suite and Flipping H1 ETMY Bias Sign
J. Kissel
We're taking the IFO out of observation intent and beginning measurement prep for flipping the H1 ETMY bias sign. Stay tuned for detail aLOGs.

PCAL to DARM Transfer Functions complete. We're going to quickly run an A2L measurement, then open the beam diverters. After which, we'll try to preserve the lock by transitioning over to ETMX for DARM control. However, this will require turning the ETMX HV ESD driver back ON, and we're on 50% confident that the IFO lock can survive that turn on transient. Wish us luck!

In the kappa corrected parameter file for the measurements taken on Oct 15 we used average kappas over 1 hour calculated from SLM tool starting at GPS 112894560. The values are listed below:
DARMOLGTF model vs. meas. comparison plots from measurements prior to ESD bias sign flip are attached to this report.
Parameter files for these measurements and updated comparison scripts are committed to calibration SVN (r1673):
