To get a better idea of how the picomotor movements effect the movement of the Hartmann beam across the ITM, we decided to move them by a larger amount. To make sure there isn't any clipping I went out to the HWS table and removed the Hartmann plate to view the beam on the ccd while moving.
The following moves were made:
ITMX upper periscope mirror: 700 counts to the right
ITMX lower periscope mirror: 500 counts to the right
ITMY upper periscope mirror: 500 counts to the left.
Attached are the current picomotor settings.
A ring heater test will be coming soon.

After a discussion at the commissioning meeting about using CO2X for a contrast defect measurement, we moved the Hartmann beam for ITMX back to where it was before this comment in order to make an attempt at centering CO2X sometime tomorrow. The plan is to do a contrast defect measurement and have CO2X (about) centered sometime before Friday so we can use CO2X to improve it on Friday.
