The two scans of the arms offer a first rough evaluation of the mismatch before switching on the PR RH and when the temperature was close to the steady state.

Plot 1 is an overview of the first scan (RH OFF): mismatch roughly 1.5% North Arm and 1% West Arm

Plot 2 is the second scan of the arms (RH ON, 21:12 UTC): mismatch roughly 3% North Arm and 1.8% West Arm

The compensation via meniscus lens on SIB1 has not been performed since it is preferable to wait for the transient to be fully completed.
