I've set up the HWSY CCD to be close to the conjugate plane of ITMY_HR. There are four beams coming from this region (ITM HR, ITM AR, 2x CP_AR). If the angular separation between them is relatively small, they will make it through all the apertures in the system and also show up in the HWS image. We see this with one of the CP AR reflections:

If we can - we'd like the CP offset set to -400 counts (subject to noise investigations).

H1:SUS-ITMY_R0_OPTICALIGN_P_OFFSET = -400 (just ITM HR beam, no CP_AR beam)

H1:SUS-ITMY_R0_OPTICALIGN_P_OFFSET = 100 ( ITM HR beam, CP_AR beam encroaching)

H1:SUS-ITMY_R0_OPTICALIGN_P_OFFSET = 500 (fully both ITM HR beam & CP_AR beam)
