Mark B. (This work was mostly done Friday 12/7 but I wanted to check a few things before posting.) After the M3UL OSEM was sorted out (see 4840), I went on to get all the matrices and settings checked out and the damping working. I ran prepare.m to be sure all the filters were loaded. I entered all the M1/M2/M3 OSEM2EUL and EUL2OSEM values from the output of make_sushlts_projections.m. I set SENSALIGN and DRIVEALIGN to the identity matrix. I set the signs in M1 COILOUTF to give +ve sensor response for +ve offset. The final values were -1, -1, +1, +1, -1, +1. This agrees with the settings previously used on the triples test stand but differs in SD from E1100109-v2. I set the signs in M2 and M3 COILOUTF per E1100109-v2. I found by trial and error a set of damping gains that gave stable damping, but these can probably be improved: -0.5, -2, -1, -0.02, -0.01, -0.04.
