I ran the current version of the calibration pipeline over a stretch of O1 data to reproduce the kappas and compare to those in the C02 frames. The filters file used was aligocalibration/trunk/Runs/O1/GDSFilters/H1DCS_1131419668.npz, as suggested by the calibration configuration page for O1: https://wiki.ligo.org/viewauth/Calibration/GDSCalibrationConfigurationsO1#LHO_AN2 The agreement looks quite good. Time series plots of the kappas and the cavity pole are attached. The start time used here was 2016-10-04 12:41:19 UTC (GPS 1127997696).
