  1. HES HKS meeting T.Gogami 7/13/2010

  2. Contents • reading tracking code • chi square • initialization • ordering

  3. chi square initialization • HTRACKING /h_track_fit.f chi square initialization It looks fine in code DEF : Σ(residual/sigma)2/NDF = χ2

  4. DEF : Σ(residual/sigma)2/NDF = χ2 Σ(residual/sigma)2/NDF - χ2 = 0 52Cr target Run ID : 77124 • track is ordered in same event number • small  middle  large

  5. Summary and To do • Summary • Reading tracking code • pattern_recognition , find_space_point, track_fit, h_physics • chi square • initialization  OK • Σ(residual/sigma)2/NDF - χ2 = 0 • χ2 OK • order ? • To do • chi square ordering • residual 52Cr target Run ID : 77124

  6. End

  7. degrees of freedom hnfree_fp(itrk) = hntrack_hits(itrk,1) – hnum_fpray_param hnum_fpray_param = 4 6 hits requiredfor each layers
