New GDS filters for LHO with better high-pass filters

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.
