J. Kissel, K. Kawabe I've taken L, P, and Y driven transfer functions of the final/bottom/optic/M3 stage of H1 SUS PRM to gather what the longitudinal-to-pitch cross coupling "typically" looks like for an HSTS. Also, I've compared the results against the HSTS dynamical model, just because I'd never focused on how poorly the off-diagonal elements of the model reproduce reality. Keita had asked me for the information to help validate the recent PRC spot position measurement LHO aLOG 40477. Attached are the results and the hacky, non-svn'd script used to generate it. #slapsownwrist Data lives here: /ligo/svncommon/SusSVN/sus/trunk/HSTS/H1/PRM/SAGM3/Data/ 2018-02-13_2350_H1SUSPRM_M3_WhiteNoise_L_0p01to50Hz.xml 2018-02-13_2350_H1SUSPRM_M3_WhiteNoise_P_0p01to50Hz.xml 2018-02-13_2350_H1SUSPRM_M3_WhiteNoise_Y_0p01to50Hz.xml
