Sheila, Elenna

I have commissioned the DC centering on the POP X WFS. This uses DC6 pitch and yaw. I made OLG measurements of both loops, setting them to have a UGF around 0.5 Hz. I had to add additional loop gain to get this UGF, similar to the REFL WFS centering.

Measurements saved in [userapps]/asc/h1/templates/DC_centering

Sheila is adding this centering loop to the ISC_DRMI guardian to engage when we lock DRMI.

We should probably also add "PM1 [P/Y] clear" buttons to the DC centering page.

I also edited the ISC_DRMI guardian to clear teh PM1 suspension when it goes to Down.
