lowered the threshoold for FSS trasnmitted light
[Sheila and Kiwamu]
The FSS wasn't locking this morning, interrupting PMC's lock. Lowering PSL-FSS_RESONANT_THRES from 0.9 to 0.5 fixed the issue. The alignment on the FSS reflection camera looked bad. It has been unclear why the FSS alignment kept drifting in pitch.
