The VVF command I used in July to determine the D** fraction to be used in mx unfolded fits is ./subVirFit.pl -que kanga -cm CM2 -debug -novarfit -small -tmodel -notunbinmes=3 -rew 12 -wF sysWd/HFAGCombWin06_3d_0.txt -opt 1 -fitdss 1 -flag fitdss1_nounf_nofixcount -countmc -opt 1 sets the 3-parameter fit, -fitdss 1 is used to set the other component equal to D**lnu decays. Concezio.
