Angular noise budget

here is reported the partial noise budget of the angular loops using the measurements of last friday jan 16th. Specific injections has been made in order to both measure the coupling and obtain information to calibrate the several error signals. full budget needs to be performed.

here is the estimated calibration coefficient to have the ASC_DOF_CORR spectra in urad.

These coefficients have been found to overlap the measured OLTFs with the theoretical ones.

ggDpTX=2.4300
ggDpTY=0.3704
ggPRTX=0.8547
ggPRTY=4.5100
ggBSTX=1.9000
