Hi all, I've managed to have all the machinery well in place and I've just produced a webpage that contain documentation and 'sample' results. http://www.slac.stanford.edu/~asarti/recoil/envelop For my study I have used those two files in ~rfaccini/scra phot7trk7/alldata.root (data) ksFix2/allgeneold.root (generic) I'm going to start the production of all variables (mx & mm2) with a big number of trials (~50) tonight. This is maybe a silly question but: why we're not dumping the qtot info at tree level in recoilNtp.cc? --> Ric needs to rerun rootfiles with qtot info in if we want to study that quantity!!!! Output is going to appear in $BFROOT/work/a/asarti/envelop. In order to understand-use the output please refer to: http://www.slac.stanford.edu/~asarti/recoil/envelop Thanks to all, Alessio ______________________________________________________ Alessio Sarti Universita' & I.N.F.N.
