I redid the baffle PD alingment today:

Baflle PD 1: 203.4 Pit -236 YAW

Baffel PD 4: 272.4 PIT -297.1 YAW

Aligned: 237.9 PIT -266.5 YAW

This is only a 3 urad change in Pitch from the save values, 1 urad in yaw.  I saved these new positions.

I also wanted to see if we can use the ITMX Gig E camera instad of the baffle PDs for TMS pointing.  I unlocked the IMC and misalinged MC2, and mislianged the PZTs on ISCEX.  In this situation there should be no IR or Green on ITMX, but I still see some spots on the camera, maybe these are from an OPLEV?  The pixel sum is between 900 and 1600. (exposure is set to 100000).  At least in single shot, it doesn't seem like we can use the camera to replace the baffle PDs. 

I moved PR3 by about 1 urad in TAW and half a urad in pitch to center the beam on the ISCT1 camera. 

Then an earth quake hit (maybe 6.7 in Chile).  The 0.03-0.1Hz seismic band has been above the uper limit of the FOM chart for about an hour.
