SR2 M2 UL AOSEM swapped
Today, Travis swapped out the problematic AOSEM (FRS Ticket 5058)
| OLD (S/N 232) WAS | NEW (S/N 594) IS | |
| OLV | 24,100 | 26,600 |
| OFFSET | 12,056 | 13,300 |
| GAIN | 1.244 | 1.128 |
A quick check of suspension freedom, we did a top stage V and L TF which showed reasonably placed peaks. A full suite is likely up next, as well as a check of actuation (maybe falls out with TFs).
