The results of the mX fit obtained by taking the S/P ratio in mX bins as obtained from a p1 fit mentioned below (see values in the first table below) are at http://www.slac.stanford.edu/~bozzi/scra/Ibufitcorr_fixcountdsstag/ http://www.slac.stanford.edu/~bozzi/scra/Ibufitcorr_fixcountdsstag/fitcorr_fixcountdsstagfitresults.eps http://www.slac.stanford.edu/~bozzi/scra/Ibufitcorr_fixcountdsstag/fitcorr_fixcountdsstagresults.dat compare them with the results obtained by taking the S/P ratio in mX bins (see values in the second table below) by simply fitting http://www.slac.stanford.edu/~bozzi/scra/Ibuncorr_fixcountdsstag/ http://www.slac.stanford.edu/~bozzi/scra/Ibuncorr_fixcountdsstag/ncorr_fixcountdsstagfitresults.eps http://www.slac.stanford.edu/~bozzi/scra/Ibuncorr_fixcountdsstag/ncorr_fixcountdsstagresults.dat Concezio.
