I have produced new GDS filters that incorporate the recent changes in the front-end calibration model, including the updated L2/L3 crossover. The filters can be found in the calibration SVN at this location: /ligo/svncommon/CalSVN/aligocalibration/trunk/Runs/O2/GDSFilters/H1GDS_1167602808.npz For information on the changes in the calibration model, see these aLOGs: https://alog.ligo-wa.caltech.edu/aLOG/index.php?callRep=33004 https://alog.ligo-wa.caltech.edu/aLOG/index.php?callRep=32933 https://alog.ligo-wa.caltech.edu/aLOG/index.php?callRep=32907 The filters were produced using this Matlab script in SVN revision 4095: /ligo/svncommon/CalSVN/aligocalibration/trunk/Runs/O2/H1/Scripts/TDfilters/H1_run_td_filters_1167602808.m The parameters files used (all in revision 4095) were: /ligo/svncommon/CalSVN/aligocalibration/trunk/Runs/O2/Common/params/IFOindepParams.conf /ligo/svncommon/CalSVN/aligocalibration/trunk/Runs/O2/H1/params/H1params.conf /ligo/svncommon/CalSVN/aligocalibration/trunk/Runs/O2/H1/params/2017-01-03/H1params_2017-01-03.conf /ligo/svncommon/CalSVN/aligocalibration/trunk/Runs/O2/H1/params/H1_TDparams_1167602808.conf /ligo/svncommon/CalSVN/aligocalibration/trunk/Runs/O2/H1/Scripts/CAL_EPICS/D20170103_H1_CAL_EPICS_VALUES.m Several plots are attached. The first two (png files) are spectrum comparisons between GDS and CALCS at GPS time 1167559872 (Jan 04, 2017, 10:10 UTC). Kappas were applied in making the GDS spectrum, using the EPICS from the filters file (the EPICS in the frames at this time are incorrect). The last plot contains a time series of the kappas computed by GDS and CALCS. Note that they do not agree. This is expected, as the EPICS were not updated in the front end.
