I made plots of anti-symmetric power P_AS vs. power at reflected port of OMC P_OMC_REFL during the DARM offset step measurement on September 4th, (see LHO alog #86785 and 87629).

I had to use the Beckhoff reported power for this (H1:OMC-REFL_A_DC_POWER) as the front-end channel is calibrated wrongly (see LHO alog #87648).

I also plotted the P_OMC_REFL vs.  P_DCPD, ie. reflected vs. transmitted power for the OMC.

The plots for our two measurements taken at different times during IFO thermalisation are below, both were taken when OM2 was hot.
