The reweighting 'a la Dominique (http://www.slac.stanford.edu/~fortin/newhybrid/) is now working properly in VirVubFitter The results of the tests (http://babar-hn.slac.stanford.edu:5090/hn/aux/rfaccini/ISL/vub_meet_13Apr04) show that the default include file (sysWd/dom_0.inc) returns a result very close to the prl one and that mb,a variations return systematics consistent with those quoted so far. I also checked that the proposed technique to have a single reweighting (i.e. avoid the q+ one) seems to work, within 1% also in our case. In order to run it a possible line of command is: subVirFit.pl -d -b -rew 10 -wF sysWd/dom_0.inc -debug -flag dom_0.inc -mesbin ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ relevant new part this is supposed to be our default way of reweighting from now on, so please move to it and report problems ... ciao ric
