SQZ ASC Matrix Measured and Loops CLosed

[Sheila, Haocun, Nutsinee, Terry]

We measured the SQZ ASC matrices and closed the loops.

These matrices are from ZM1 and ZM2 to AS_A and AS_B, numbers attached as below.

We use unity for the input matrices, and measured the output matrices by dithering ZM1 and ZM2, looking at how much PITCH/YAW change on AS_A and B.

All four loops of SQZ_ASC are also closed, working well with some filters added in.

MOre details will be found in the SQZ Wiki.
