As part of the estimator work, we measured and calculated OSEMINF gains (85907) and compensating gain filter modules for the DAMP bank (86026). We believe these new values to be correct, so we have gone ahead and permanently updated the OSEMINF gains as well as turned on the compensating gains in FM7 in the DAMP filter bank for SR3.
This update means that there will be a difference in the apparent location of the DAMP INs, but this is just because of the change in the OSEMINF gains. These gains were changed (along with the compensating gains filter modules turned on) at 2025-07-29 16:58 UTC. They were put into SDF safe and will be saved in OBSERVE once we get there.
| OSEM | Old OSEMINF gain | New OSEMINF gain |
| T1 | 1.478 | 3.213 |
| T2 | 0.942 | 1.517 |
| T3 | 0.952 | 1.494 |
| LF | 1.302 | 1.733 |
| RT | 1.087 | 1.494 |
| SD | 1.290 | 1.793 |
The compensation gains put in in the DAMP filter bank are in FM7, and they are the following:
L: 0.740
T: 0.732
V: 0.548
R: 0.550
P: 0.628
Y: 0.757
Accepted these changes in SDF.
