Given that h1susb123 had an emergency upgrade to 20-bit DACs this morning, we need to do "the usual" cheat to ensure the upstream loops that use the stages that got upgrade don't notice a difference -- add a "20bitDAC" gain of 4.0x to the COILOUTF banks in FM10 of any stage that got the upgrade from 18- to 20-bit DACs. This accounts for the change in calibration from 20V / 2^18 to 20V / 2^20.
This has been done for the

- H1 SUS ITMY R0 F1F2F3SD
- H1 SUS ITMY M0 LFRT / R0 LFRT
- H1 SUS ITMY L1 ULLLURLR
- H1 SUS ITMX M0 F1F2F3SD

COILOUTF banks, corresponding to all the stages that got upgraded this morning.
Attached are the automatically generated "diff" screens for each model showing that I added the gain(4) design string in each 9th module (counting starting a 0, that's FM10) to all of the above mentioned OSEMs.
I then hit "LOAD_COEFFICIENTS" on each user model's GDS_TP screen (which clears the diff).
