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