  35. Summary • Reconstruction results of ME+2 SLMs in ZCMS are comparable to Photogrammetry (PG) data at 0T. Positions of top of the DCOPS, coded targets on the skin and alignment pins are compared with PG. • Resolution and sensitivity to relative changes 68 micron • Accuracy of CSCs and DCOPS 491 micron (against PG) • Drawings show the detail view of DCOPS dowel pins and alignment pins wrt CSC center. • Reconstruction in Rphi has started to work with correct geometry input. • Immediate Item to take care of Expand Rphi reconstruction to other SLMs. Muon Alignment, CMS Week December 2007 - S.
