11. Pseudorapidity coverage Hits from inner disk Hits from outer disk overlap

12. Discussions There are some holes inside FPix fiducial envelope. Pseudorapidity coverage compared to figure35 from CMS document ( The CMS Experiment at the CERN LHC 1/6/2008) estimation from CMS doc fig. 35 eye ball estimation from the histogram(cosmic ray) Inner disk eta = ~1.5 : ~ 2.3 ~1.6 : ~ 2.35 Outer disk eta = ~1.8 : ~2.6 ~1.9 : ~ 2.7 Overlap region ( 2 hits) : ~1.9 : ~ 2.4
