New Monuments at End-X for NCal Position Survey (LHO WP 8426)
J. Oberling, T. Sadecki
In perparation for surveying the position of the new NCal system at End-X, Travis and I placed new monuments for equipment setup. We placed 2 new floor monuments (IAM-EX-T6 and IAM-EX-T7) and added 1 new vertical height monument (BM#5). New monument coordinates:
- IAM-EX-T6
- X: 4008784.0 mm
- Y: -4032.0 mm
- IAM-EX-T7
- X: 3998294.5 mm
- Y: -4032.0 mm
- BM#5
- Z: -1.0 mm w.r.t. BSC09 = 0.0
D1100291 has been updated to -v7 to reflect these 2 new floor monuments; I have been unable to find a repository of EX height monuments on the DCC to document the new height monument, so this entry will suffice for now. This completes LHO WP 8426.
