IMTX recovery

IMTX triped (GS13s and T240s) this morning, I don't know why. ( first attached plot)

I had some trouble brining it back, which might be because we paused the guardian and used the command scripts for Jim's measurement on friday.  I followed Jamie's instructions from alog 11246, this didn't work verry well.  At first the indivdual stage guaridans compalined about gains that weren't set corectly (all the ISO gains were set to 0)  I paused everyone, fixed the gains, and unpaused again.  Stage 1 guardian complained about filters which weren't set correctly (which was true, they weren't set correctly.) and stage 2 went ahead and tried to isolate, then the watchdog tripped. 

I paused everyone again, set the fitlers the way the guardian was asking for, and unpaused again.  One more time stage 2 tripped, which is the second plot attached.  after reseting this one last time I think that the gaurdian has suceeded in bringing it back.

One more trip, the reson for this trip is not clear. There is no one working out by ITMX, the gain switches are all set correctly, sensor correction is on from the ground to stage 1 XYZ, we have Tbetter on all blends except for RZ which is Tcrappy

Also, the plotting script failed for some of the first trips on ITMX this morning.
