Today I took "unbiased" OLGs of PRC2 P and Y (67187). I have plot the measurements with error shading.

PRC2 P has a UGF of about 0.12 Hz with a phase margin of 46 deg. PRC2 Y has a UGF of about 0.17 Hz with a phase margin of 53 deg.

This lines up with the target UGF Gabriele and I had when we redesigned this loop (69108).

You can find the measurement templates, exported data, and processing code in '/ligo/home/elenna.capote/DRMI_ASC/PRC2'.

The templates for the these measurements are also saved in [userapps]/asc/h1/templates/PRC2 as 'PRC2_{P,Y}_olg_broadband_shaped.xml'.

As a reminder, PRC2 controls PR2 and is the "only" ASC loop that controls the PRC. We do not run PRC1 in full lock, and we only control PRM angle with the (very low bandwidth) camera servo. PRC2 is currently sensed on a combination of REFL RF9 WFS.
