The results are listed in the following table. +X is downwards. +Y points to larger angles for the left arm. +Y points to smaller angles for the right arm. During E01-001 there was a problem with the left arm collimator and the collimators were surveyed between the experiments on 5/30/02. My guess on the precision of the survey is somewhere between 0.2 and 0.5mm. The distance from hall center to left arm sieve is 118.34cm. The distance for hall center to the right arm sieve is 117.45cm. \layout Standard \added_space_top 0.3cm \added_space_bottom 0.3cm \align center \LyXTable multicol5 6 8 0 0 -1 -1 -1 -1 1 1 0 0 1 0 0 0 1 0 0 0 1 0 0 0 1 0 0 0 1 1 0 0 8 1 0 "" "" 8 1 0 "" "" 8 1 0 "" "" 8 1 0 "" "" 8 1 0 "" "" 8 1 0 "" "" 8 1 0 "" "" 8 1 1 "" "" 0 8 1 0 0 0 0 "" "" 0 8 1 0 0 0 0 "" "" 1 8 1 1 0 0 0 "" "" 2 8 1 0 0 0 0 "" "" 2 8 1 0 0 0 0 "" "" 1 8 1 1 0 0 0 "" "" 2 8 1 0 0 0 0 "" "" 2 8 1 0 0 0 0 "" "" 0 8 1 0 0 0 0 "" "" 0 8 1 0 0 0 0 "" "" 0 8 1 0 0 0 0 "" "" 0 8 1 0 0 0 0 "" "" 0 8 1 0 0 0 0 "" "" 0 8 1 0 0 0 0 "" "" 0 8 1 0 0 0 0 "" "" 0 8 1 0 0 0 0 "" "" 0 8 1 0 0 0 0 "" "" 0 8 1 0 0 0 0 "" "" 0 8 1 0 0 0 0 "" "" 0 8 1 0 0 0 0 "" "" 0 8 1 0 0 0 0 "" "" 0 8 1 0 0 0 0 "" "" 0 8 1 0 0 0 0 "" "" 0 8 1 0 0 0 0 "" "" 0 8 1 0 0 0 0 "" "" 0 8 1 0 0 0 0 "" "" 0 8 1 0 0 0 0 "" "" 0 8 1 0 0 0 0 "" "" 0 8 1 0 0 0 0 "" "" 0 8 1 0 0 0 0 "" "" 0 8 1 0 0 0 0 "" "" 0 8 1 0 0 0 0 "" "" 0 8 1 0 0 0 0 "" "" 0 8 1 0 0 0 0 "" "" 0 8 1 0 0 0 0 "" "" 0 8 1 0 0 0 0 "" "" 0 8 1 0 0 0 0 "" "" 0 8 1 0 0 0 0 "" "" 0 8 1 0 0 0 0 "" "" 0 8 1 0 0 0 0 "" "" 0 8 1 0 0 0 0 "" "" 0 8 1 0 0 0 0 "" "" 0 8 1 0 0 0 0 "" "" 0 8 1 0 0 0 0 "" "" 0 8 1 0 0 0 0 "" "" 0 8 1 0 0 0 0 "" "" 0 8 1 0 0 0 0 "" "" 0 8 1 0 0 0 0 "" "" Date \newline Coliimator \newline Right arm \newline Left arm \newline 4/4/2002 \newline \newline X(mm) \newline Y(mm) \newline encode \newline X(mm) \newline Y(mm) \newline encoder \newline \newline 6msr \newline -0.11 \newline -2.72 \newline .6120 \newline +0.02 \newline -1.55 \newline .6155 \newline \newline sieve \newline +0.07 \newline -1.06 \newline .3605 \newline -0.02 \newline -0.21 \newline .3637 \newline 5/30/02 \newline 6msr \newline \newline \newline \newline +0.07 \newline -1.81 \newline .6193 \newline \newline sieve \newline \newline \newline \newline -0.01 \newline -0.50 \newline .3682 \the_end
