We found an error in the GDS calibration filters originally generated for ER7 and discussed in LHO alog #18813. Originally, we had double compensated for the AI filter in the actuation chain and the AA filter and OMC whitening poles in the sensing chain. This was corrected on June 4, 2015 (at GPS time 1117505816) and new plots of the filters are attached. The new filters file is located in the calibration SVN: aligocalibration/trunk/Runs/ER7/GDSFilters/H1GDS_1117505690.npz.
