J. Kissel, E. Goetz I've gathered our "bi-weekly" calibration suite of measurements to track the sensing function, and ensure all calibration is within reasonable uncertainty and to have corroborating evidence for a time-dependent detuning spring frequency & Q. Evan will post analysis results later. The data have been saved and committed to: /ligo/svncommon/CalSVN/aligocalibration/trunk/Runs/O2/H1/Measurements/SensingFunctionTFs 2017-03-06_H1DARM_OLGTF_4to1200Hz_25min.xml 2017-03-06_H1_PCAL2DARMTF_4to1200Hz_8min.xml 2017-03-06_H1_PCAL2DARMTF_BB_5to1000Hz.xml This suite, again for time-tracking, took ~35 minutes from 2017-03-06, 18:02 - 18:35 UTC.
