RM1 COILOUTF signs set throughout this test as UL, LL, UR, LR = +, -, -, + (Obey's T1200015 convention) RM2 COILOUTF signs set throughout this test as UL, LL, UR, LR = -, +, +, - (Disobey's T1200015 convention) Both HAM1 doors are still OFF. LVEA is laser Hazard. 2W going into IFO. IMC was LOCKED. PRM (and IMs) were ALIGNED. REFL beam coming back from PRM into HAM1 used as optical lever. RM Damping loops are in question, so they are OFF. ISI is floating and DAMPED. Door parachute cover is clamped all the way at the top. Rahul is standing on step ladder at the -Y door of HAM1. "Toward him" is -Y "Away from him" will be +Y Offset ramps set to 10 seconds. %%%%%%%%%% RM1 %%%%%%%%%% Rahul has an IR view card positioned at RM2. RM1 PIT offset RM1_M1_OPTICALIGN_P_OFFSET 16:21 + offset 20000 16:23 - offset 20000 more negative pitches the beam up. (implying positive pitch offset pitches the beam DOWN) GOOD RM1 YAW offset RM1_M1_OPTICALIGN_Y_OFFSET 16:24 -20000 16:25 + 20000 16:26 -20000 more negative beam displaces toward rahul (-Y direction) given RM reflects the beam from ~ -X to +X, that means "towards rahul" (-Y) is i.e. -RZ i.e. -yaw 16:26 + 20000 more positive displaces away from rahul, (+Y direction) i.e. +RZ i.e. +yaw positive offset cause real positive yaw. GOOD RM actuation obeys conventions with digital signs as they are. %%%%%%%%%% RM2 %%%%%%%%%% Rahul has an IR view card positioned just before M5, and also downstream of M5 just before M6. RM2 PIT RM2_M1_OPTICALIGN_P_OFFSET -20000 16:28 +20000 - 20000 + 20000 beam up - 20000 beam down +20000 beam up positive offset reflects the beam up, i.e. negative pitch. RM2 is opposite convention. Confirmed BAD RM2 YAW + 20000 away from rahul (+Y) -20000 9:31 (no change) +20000 away from rahul (+Y) -20000 9:32 towards rahul Even tho RM reflects the beam from ~ +X to -X, that means "towards rahul" (-Y) is i.e. -RZ i.e. -yaw RM2 disobeys convention BAD confirmed as is. BBBBUUUUUUTTTTT --- the COILOUTF bank also is wrong. So, we COULD fix RM's actuation sign by installing CORRECT COILOUTF gain signs of +, -, -, +.
