Hi all, the new selection for the neutrals (LAT>0.05) and the cut on kaon id (no kaon-id < 300Mev) proposed by riccardo in http://www.slac.stanford.edu/cgi-bin/lwgate/VUB-RECOIL/archives/vub-recoil.200209/Author/article-18.html seems to have a good effect on mm2 and mx (before the fit). See old selection http://www.slac.stanford.edu/~daniele/vub/oldcomp_2/oldcomp_2-comp.html new selection http://www.slac.stanford.edu/~daniele/vub/newcomp/newcomp-comp.html In general all the comparisons are either equivalent or better than before. I am still worried about the pstar spectrum and some efficiency business in the depleted sample. Daniele
