Subject: Mode Cleaner WFS 

 

I calculated the MC1&3 Vs WFS1&2 Output Matrix today from the above measurements with koji's help.

the matrix can be generated from the m file at /cvs/cds/caltech/users/nancy/Align_Matrix/matrix.m

these values were put in, and the direction of control is sort of confirmed. I tried twiddling with the gains in the loop to get a 4*4 stable control, but could not succeed.

the mode cleaner is back locked now, and WFS matrix as well as gains are reverted to the old values.  (1.30 am)

 

The output Matrices are

Pitch

0.724
0.197
0
0
-1.448
-0.758

Yaw

0.919
0.139
0
0
-0.0106
-0.1245
