EVE Mid-shift status

After the table work, ran an Initial Alignment (it was a bit rough in that INPUT_ALIGN had trouble locking the X-arm.  Restrored PR2 alignment to where it was during the last lock, but it was still tough.  However, INPUT ALIGN finally did complete and it looked as though the entire alignment completed.  

Unfortunately, DRMI did not look good and PRMI also looked misaligned (there were short 1-2 second locks, but they are very low and so far I have not been fast enough to touch up the PRMI alignment to let ASC take over).

0314utc (814pmPT) SEI_ENV in EarthQuake state due to 6.6 from Panama/Colombia.  (Picket Fence has been orange and red.)

Will start another Initial Alignment as Sheila looks at trends.

In the end the PR3 and ISCT1 table alignment was a temporary fix to the true problem. The true problem was that the HAM-ISIs were all drifting off in Yaw (RZ) slowly, but surely, for weeks -- see LHO:69934.
