After the CPB installation and yesterday's SUS/SEI tweaks I set my equipment back up and took another look at ITMx.

• Longitudinal Error: -0.2 mm (south)
  • Tolerance: ±3.0 mm
• Lateral Error: -0.09 mm (east)
  • Tolerance: ±1.0 mm
• Veritcal Error: -0.14 mm (low)
  • Tolerance: ±1.0 mm
• Yaw: ~ +1.6 mrad (CCW)
  • Tolerance: ±50 µrad

The yaw error is only approximate, ±150 µrad or so.  Due to this large yaw error I wasn't able to get an accurate yaw measurement or a pitch measurement; getting a return beam back into the autocollimator resulted in the beam being steered off the optic.  After talking with Hugh this morning the HEPI dial indicators did not show a large yaw movement, and double checking my setup did not yield different results.  It is possible yesterday's SUS move induced the yaw error; it wouldn't take much more than pushing one side of the suspension 0.5 mm farther than the other to cause it.  Will discuss path forward with Betsy and Hugh tomorrow.
