I am not sure whether there is a difference of one between the > two sets of plots. The mean and RMS are kind-of consistent. The problem that I saw yestarday was due to a wrong call to the isAncestor function: now all the differences btw isAncestor and my code are vanished. The striking difference btw sp3 and sp4 (in the Energy spectra) is also almost vanished. The only big difference that is surviving the bug fixing is in the number of NOT truth matched neutrals two red lines in the table that you find in web page http://www.slac.stanford.edu/~asarti/recoil/neu_stu/ > > Is it possible to make a comparison for events with and without > K0S->pi0pi0 (in the generator block)?
