OPS Saturday day update

Still having alignment problems, I wasn't able to finish SRC in IA. PRMI won't stay locked for more than 2 seconds despite ok flashes. I'm thinking of trying to restore the alignment to right before we locked last night or doing another initial alignment.

Still having trouble with PRMI, the 20Hz buzz keeps killing it, but I've been able to survive longer after lowering the MICH1 gain per Sheilas instructions, I'm going to try lower it a little more and stepping more slowly through the ISC_DRMI states

Running through CHECK_MICH made it worse? Now the alignment looks bad again, AS AIR is clearly Pitched and no amount of adjusting PRM or BS seems to be helping it. I'm going to do another IA
