# Ideal coordinates of the WC survey targets. Taken from the CAD model. # # Coordinates are in the BLAST system (X towards centre of ring, Y vertically # up, Z along electron beam, origin at the target centre). # # These data are for the left sector. Right sector has opposite X value. # # These data are for the top survey targets. Bottom has opposite Y value. # # In Karen's notation these are LCT[I/M/O][U/D][I/O] for Left Chamber, Top, # Inner/Middle/Outer, Up/Down-stream, Inner/Outer. # # Note survey targets are 7.94 mm long while tooling balls are 12.7 mm long. # Their axes are NOT vertical !!! but perpendicular to the plane of the top # (bottom) outer surface of the WC. The top plane is nominally given by the # plane formed by the extreme corner targets LCTIUI, LCTIDI, LCTOUO, and # LCTODO which is NOT the same as the plane defined by the extreme corner # targets of an individual chamber! # # The following data is I/M/O, U/D, I/O, X, Y, Z [mm] # # - D.K.
