Following previous aLog (7568) on PR2 top mass transfer functions, lower masses phase 3b transfer functions have been taken and measurements data have been processed. Plots attached are showing comparison with model and other hsts measurements

(1) H1 PR2 M2 to M2 undamped TF (July 2013 in pink) against L1 PRM M2 to M2 undamped TF (July 2013 in orange) against hsts model

(2) H1 PR2 M3 to M3 undamped TF (July 2013 in pink) against L1 PRM M3 to M3 undamped TF (July 2013 in orange) against hsts model

Looking at M2-M2 TF, the two highest resonnances of pitch (3.094 Hz and 3.641Hz) are shifted down compared with the model and LLO's measurement (3.216Hz and 3.778Hz). 

Those measurements have been taken with DTT and the xml templates are located on the svn under sus/trunk/HSTS/H1/PR2/{SAGM2 or SAGM3}/Data/2013-07-15_1900_H1SUSPR2_M2_WhiteNoise_{L or P or Y}_0p01to50Hz.xml

Data, plots and scripts have been commited to the svn
