(Doug, Jason, Hugh, Betsy and CO) First look at the ETMy in chamber measurements are very encouraging. Results: Longitudinal was short by 0.5mm from absolute, tolerance is +/- 3.0mm, Lateral position is 0.35mm to the south, +/- 1.00mm Elevation position is high by 0.35mm, tolerance is +/- 1.0mm Optic is set lightly on EQ stops, but for a first look to identify any need to move the ISI or SUS this is very reasonable results. The arm cavity baffle was rough positioned to accommodate the line of sight from the spool and currently rests unattached on its installation table so use caution when working around it. When fully pay loaded, cabled with the ETM suspended we will do the the fine alignments of the positions and optic angles
The vertical position is actually high by 0.9 mm, not by the 0.35 mm originally stated.
