bin p 1GeV to 2 GeV, pt 0.3 GeV to 0.5 GeV Bin of VTPC1 only tracks, averything looks OK, some ot tracks are too short, probably they should be rejected. From time to time I see couple of points laying on the track but not assigned to it positives 14 9pt track, close to it another track 16 7pt track 19 8pt track 28 very close tracks? 36 part of track seems lost (close to chamber edge) 48 decay? 50 9pt track 53 10pt track 54 do not see large part of track in chamber, a/p=100% ??? 55 9pt track 57 decay? 61 couple of points not assigned to track 64 very close tracks 67 wrong momentum fit 91 8 pt track negatives 3 7pt track 10 7pt track 12 9pt track, couple of points seem lost 16 big difference between mom. fits 32 big diff. between mom. fits 40 9pt track 42 why seen only on one TPC? 44 decay 52 V0 63 7pt track 74 9pt track 82 big difference between fits 98 decay? bad mom. fit Distributions corresponding to theese bins can be found in my public (~jurajb/public/eyescan), they are in postscript files, first part denotes type of distribution, second bin in p, third bin in pt, last charge. For example b30-50_07-09_neg.ps in distribution of impact parameters for p form 30 to 50, pt form 0.7 to 0.9 for positives.
