Lenght to Pitch decoupling filter
More detail will follow, but we determined how to get the length to pitch decoupling filter (jsut a confirmation), and using the Quad models we generated the length-to-pitch decoupling filter, for placement in the 'DriveAlign Matrix' in the M0 path.
The frequency dependent response is -Length-to-Pitch / Pitch-to-Pitch (with a gain factor).
Using plotallquad_dtttfs.m and quad_l2p.m in /ligo/svncommon/SusSVN/sus/trunk/QUAD/Common/MatlabTools, I generated Dl2p_2012_07_13.mat. Is has a frequency vector and the coupling vector.

I modified the script to include the M0 Long-2-Pitch and the Pitch-2-Pitch transfer functions as well.
