I have clarified my elog from last night to indicate that the sensing matrix in the "33MHz cancellation" configuration was measured with the PRMI held on REFL55 I&Q.
Also, I just re-read my control room notes from yesterday, and I typed the wrong demod phases into the table last night. The elog has been edited. Most significantly, the REFL33 demod phase did not change by 70 degrees. It did change by 10 degrees, but that is likely from the fact that it was formerly tuned for PRCL in PRFPMI, and last night I tuned it for PRCL in PRMI-only.
