OLV RM1 RM2
Open light values have been measured on RM1 and RM2
| OPTIC | OSEM | Open Ligh Value (cts) | Gain | Offset | Serial Number |
| RM1 | M1UL | -32768 | -0.916 | 16384 | 1105240 a |
| M1LL | -32768 | -0.916 | 16384 | 1105240 b | |
| M1UR | -22268 | -1.347 | 11134 | 1105240 c | |
| M1LR | -29171 | -1.028 | 14586 | 1105240 d | |
| RM2 | M1UL | -26656 | -1.125 | 13328 | 1105238 a |
| M1LL | -32768 | -0.916 | 16384 | 1105238 b | |
| M1UR | -32708 | -0.917 | 16354 | 1105238 c | |
| M1LR | -32768 | -0.916 | 16384 | 1105238 d |
damping gains have been set to
-30 in long
-0.02 in Pitch
-0.02 in Yaw
the safe snapshot has been commited to the svn
I used the script "[OSEM2EUL, EUL2OSEM, SENSALIGN, DRIVEALIGN] = make_sushtts_projections" in /HTTS/Common/MatlabTools/ to generate the matrices for RM1 and RM2
They have been automatically filled with fill_matrix_values.m
The values are
OSEM2EUL:
0.2500 0.2500 0.2500 0.2500
10.3681 -10.3681 10.3681 -10.3681
-10.3681 -10.3681 10.3681 10.3681
EUL2OSEM matrix :
0.2500 10.3681 -10.3681
0.2500 -10.3681 -10.3681
0.2500 10.3681 10.3681
0.2500 -10.3681 10.3681
Safe snapshot has been saved for both RM1 and RM2
