I've produced new filters for use in the GDS calibration pipeline with improvements to the high-pass filters. These filters are otherwise the same as those mentioned in LHO aLOG 45428. The new filters can be found in the calibration SVN at:
aligocalibration/trunk/Runs/PreER13/GDSFilters/H1GDS_1227048227.npz
They were produced from SVN revision 6059 with these parameters files:
The changes made in the high-pass filters were:
The first three of the attached plots show comparisons of the time-domain filters to the frequency-domain models. The 4th plot shows ASDs produced by GDS using this filter and by CALCS. The last plot is a transfer function beteen CALCS and GDS.
The primary and redundant GDS calibration pipelines were restated around GPS 1227050381 to pick up these new filters.
