CHAMP:Engineering Measurements
CHAMP-MIRC offsets
2010-09-07a: We found fringes with MIRC putting the Ealing-mount IR4s to 90615)
2010-09-07b: We put the MIRC Ealing mounts to "good" position (i.e. co-phased with PAVO) and adjust Newport RETRO mounts to find fringes on MIRC. Then, we search with Dichroics to find fringes for CHAMP. Unfortunately, fringes are out of the the Dichroics range, so we have to move them away from "good".
2010-09-07c: We put the MIRC Ealing mounts to values close to the good position and adjust Newport RETRO mounts to find fringes on MIRC. Then, we search with Dichroics to find fringes on CHAMP:
IR1: -
IR2: (Beam 1/2), MIRC: IR1=40350 (moved 2cm from good position), IR2=80449 ("good" position)
IR3: 182150 (Beam 2/3), MIRC: IR2=80449, IR3=66000 (both "good" position)
IR4: 208350 (Beam 3/4), MIRC: IR3=66000 (good position), IR4=71615 (moved 2cm from good position)
