keyword=HRS Front and Back Floor Marks [a.k.a. poor man's survey]
I went under the right and left HRS and checked the back and front floor marks. (photo 142-7591 shows both front cameras)
Front 18 degrees, Vernier -34.2 mm: photo 142-7604
Back 18 degrees, Vernier -21 mm: photo 142-7605
Left Arm
Front 12.5 degrees, Vernier +31 mm: photo 142-7599
Back 12.5 degrees, Vernier +10 mm: photo 142-7593
(left back still had one of the super-Rosenbluth floor plates)
From this we should be able to figure out the mispointing of the spectrometers.
Negatives verniers are farther from beam line and positive towards the beam line.
