Hi, I have made some more plots: Using a finer mm2 bining and varying the binning of Nc+Nn: http://www.slac.stanford.edu/~menges/Vub/Fitter.new/rescomp_fit2024_xyz_nreR14_rms.eps The change in Nc+Nn is not improving anything. Using a binning in mxhad and mm2: http://www.slac.stanford.edu/~menges/Vub/Fitter.new/rescomp_fit2527_xyz_nreR14_rms.eps And the comparision plot: http://www.slac.stanford.edu/~menges/Vub/Fitter.new/rescomp_fit_xyz_nreR14_rms.eps Cheers, Wolfgang ----------------------------------------------------------------------------- Wolfgang Menges Queen Mary, University of London SLAC, MS 35 Mile End Road 2575 Sand Hill Road London, E1 4NS, UK Menlo Park, CA 94025, USA ++44 20 7882 3753 ++1 650 926 8503 [log in to unmask] -----------------------------------------------------------------------------
