QUAD M0 and R0 Yaw Diagonalization
The M0 and R0 diagonalization measurements for the Yaw DoF were run today using the DTT templates "x1_susquad_M0_yaw_diag_111103.xml" and "x1_susquad_R0_yaw_diag_111103.xml", located in the SUS SVN in '~/SusSVN/sus/trunk/QUAD/X1/Common/dtt_templates/'.

The first plot is of the M0 stage. The F1 OSEM is roughly ~20dB isolated from the Yaw DoF for the M0 stage.  All other OSEMs are at least ~35dB isolated from Yaw.  The Yaw excitation was a 1.353Hz sine wave with 250cts of amplitude.

The second plot is of the R0 stage.  OSEMs "F1" and "SD" are about ~25-30dB isolated from Yaw.  The other two OSEMs are at least ~35dB isolated.  The excitation was a 1.3Hz sine wave with 35cts of amplitude.
