J. Kissel I've taken new DARM Open Loop Gain and PCAL2DARM transfer functions for the bi-weekly(-ish) full-frequency-span confirmation of the time variation in calibration / IFO parameters. As a by-product of these two transfer functions, we're able to confirm that the front-end, CAL-CS, DELTAL_EXTERNAL calibration (and therefore the low-latency GDS pipeline output) is still within the desired precision. I attach screenshots of the measurements. They will be processed in greater detail tomorrow, once we have the evening's kappa values (i.e. what the calibration lines are telling us the systemaic errors are in the model parameters). Stay tuned, but things continue to look exquisite. Great job CAL team!
