Hi all, the work done on envelops is presented in http://www.slac.stanford.edu/~asarti/recoil/envelop I've done the chisquare study (plots are still growing: I have ~1k jobs in queue (medium) for the remaining 25 trials...: the statistics is not complete): plots are shown and documented in the webpage. I still need time to digest them. Ric is taking care of 'Visual' distribution comparison... Cheers, Alessio ______________________________________________________ Alessio Sarti Universita' & I.N.F.N.
