ETMy P-cal Periscope IAS Alignment
Doug, Rick, Craig
Friday we finished the P-Cal periscope installation and alignment
Final results after periscope lock down with the steering mirrors added:

Pitch: -6.0 micro radians (desired +/- 200 micro radians)
Yaw: 22 micro radians (desired +/- 200 micro radians)

Longitudinal: EDM reading 1,575 mm (desired 1,574.56 mm) L= 5,629.8 mm (HR to monument) - 4055.237 mm Periscope to HR face)= 1,574.56 tolerance +/- 3.0 mm

Latitude: within the 0.5mm width of the vertical target cross hair. (tolerance +/- 2.0 mm)
Vertical: within the 0.5mm width of the horizontal target cross hair. (tolerance +/- 2.0 mm)
Roll: within the 0.5mm width of the vertical horizontal target cross hair. (tolerance +/- 2.0 mm)

All measurement made in relationship to the beam line perpendicular to the HR face (00. 02'.12" pitched down (639 micro rads. total station pointing up -89deg 57'48"
