Like we did with SR3 (86070), I've updated the OSEM calibration for PR3. The updated OSEMINF values, along with the compensation gains that get put into the DAMP filter bank were calculated and put in (86222). Today I updated the PR3 OSEMINF gains and put the compensation gains into FM7 in the DAMP filter bank and turned them on. I've accepted these in the safe sdf.
The update to the OSEMINF calibration means that it will look like there is a change in alignment for PR3, but this is not real. Here is what the alignment change looks like: ndscope. These changes were made at 2025-08-19 16:27:57 UTC
OSEMINF changes
OSEM | Old OSEMINF gain | New OSEMINF gain |
T1 | 1.161 | 2.055 |
T2 | 0.998 | 1.544 |
T3 | 1.047 | 1.511 |
LF | 1.171 | 1.862 |
RT | 1.163 | 2.063 |
SD | 1.062 | 1.639 |
The compensation gains put in in the DAMP filter bank are in FM7, and they are the following:
L: 0.596
T: 0.648
V: 0.617
R: 0.617
P: 0.670
Y: 0.596
