    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.
