I remeasured the CARM pole as we did in April.

CARM pole = 0.595 +- 0.007 Hz.

The method was pretty much the same as before, I just looked at the Input RIN using H1:PSL-ISS_SECONDLOOP_RIN_OUTER_OUT_DQ rather than H1:IMC-IM4_TRANS_NSUM_OUT_DQ (but these have a TF of unity, so they witness the same thing).
My B channel this time was H1:LSC-POP_A_RIN_OUT_DQ, this corresponded well with using the arm transmission as B channels as well.
The coherence is marginal, I fit only to points between 13 and 29 Hz.  Could bias this estimate.
