Setting up DC centering for POP X

Sheila, Jennie W, Elenna,

 

We need to set up two DC centering loops for the PM1 suspension using the new in-vac POP_X PD.

Sheila copied over the H1:ASC-DC1_P and Y filters to the H1:ASC-DC6_P and Y filter banks after checking the shaping of these loops, and that the input and output matrices for both DOFs direct POP X  DC input -> DC6 -> PM1. We loaded the coefficients in H1:ASC model.

Elenna put in gains to match those used by DC1 and turned on the corresponding filters in the DC 6 filter banks. The inputs are off for now and we can test these later.
