In 83662 it was discussed that the osem compensating filter z:p = 10:0.4 wasn't as accurate as it should be. Jeff worked out that the zero and pole from the satamp are 0.3835 Hz and 10.6103 Hz, respectively, so our compensating filter should be the opposite of that, with a zero at 10.6 Hz and a pole at 0.38 Hz.
Today we updated those filters for PR3 and SR3. They appear in all three stages in the initial OSEMINF filter bank (FM1) (H1:SUS-PR3_M{1,2,3}_OSEMINF_{sensor}) as well as in all three stages of the watchdog bandpass filter bank (FM6) (H1:SUS-PR3_M{1,2,3}_WD_OSEMAC_BANDLIM_{sensor}). So where before those filters there were 10:0.4, they now read 10.6:0.38 and have these updated zero and pole values. We've loaded in the coefficient changes.
I've attached the script that we used to update these filters below. It's an edit of Jeff's script in 80189

Checking on the sat amp compensation filter change from 10:0.4 to 10.6:0.38, we noticed that it has the net effect of decreasing the OSEM signal with respect to before the change [see first attachement].
The compensation would make the OSEM corrections from 83605 about 5-6% larger, which we can estimate by looking at the ratio between the new compensation filter and the old compensation filter. [see second attachment].
