  1. Alignment marks VELO Top Outer and inner frame for C-side rotm rotd rotu ritu ritd Upstream Downstream rimm rimd ribu ribd robu robd Bottom Data points are plotted on a grid where the design values are at the grid points( like [-2,2,3] for the center frame point rotd, and [-1,1,2] for the alignment frame point ritd). Data are plotted such that for the deviations holds: 1 unit corresponds with 1mm.
