Hoi, just for comparison, my summary plots can be found in "new" MC: trk=3, gam=0: http://www.slac.stanford.edu/~ursl/talks/110502/anaQA-f00/main-new.ps trk=7, gam=7: http://www.slac.stanford.edu/~ursl/talks/110502/anaQA-f01/main-new.ps "old" MC: trk=3, gam=0: http://www.slac.stanford.edu/~ursl/talks/110502/anaQA-f00/main-old.ps trk=7, gam=7: http://www.slac.stanford.edu/~ursl/talks/110502/anaQA-f01/main-old.ps Ignore the cocktail in both cases, it has not been split into the two samples "new" and "old".
