Hi all, I produced the plots for the resolution vs mm2 running on the the subsamples with and without Ks bug (Ric's fix is switched on): without bug: http://www.slac.stanford.edu/~daniele/vub/compvcbmm2_nobug.eps with bug http://www.slac.stanford.edu/~daniele/vub/compvcbmm2_bug.eps Comments: - difference in resolution with and without Ks bug for mm2<0 - without bug the dependence is similar to the one shown in the BAD - still some differences, probably due to non-retuned kinematic fit Daniele
