Actuator polarity check in ETMY
[Okutomi, Fujii, Yamada]
We checked actruators' polarity of the ETMY cryopayload. We put offset on each actuator to see their moving direction. For MN, it seems current value is correct.
For IM, V1:-1, V3: -1, H1: -1, H2: +1, H3: +1 (We couldn't verified V2.) Also, we found a lot of coupling between Yaw and Pitch, so we need to hurry up the diagonalization of actuator matrix.
For TM, H2: +1, H3: +1. And we found serious mistake. H1 and H4 are swapped. We'll go to EYV to fix this problem on Monday morning.
