Input Mirrors Restored

Went though the recovery procedure for the IM mirrors after HAM2 SEI trips & they are now at their nominal values.  (remember:  These are downstream of the IMC...I always need to remind myself.)

IMC Status:  Not Locking

• MC Not locking.  MC REFL video spot looks off in both pitch & yaw.
• Since IMC was not re-locking, looked at MC1-3 (they were all within 5um).  I restored them to their values when the IMC was locked.  Still no IMC locking.
• Cleared Histories for IMC WFS.  No luck here.  ----This changes the value of the IMC PZT pit/yaw values.

As noted above, the IMC Refl video spot looked to be off in pitch & a little off in yaw with regards to the MC REFL camera (attached).  I have to be honest that I don't know what the location of this spot looks like for a nominal state because the IMC usually quickly locks up. 

After Clearing Histories (noted above), the IMC PZT values stepped to new values.  (6-hr trend attached).

Approaching limit of what I can do without the help of an expert.  My guess is that the PZT mirrors would be a remaining knob I have not tried, but I would prefer to NOT touch those mirrors without an expert.  (Will go through alogs to see if I can find more help.)
