i am not 100% sure to understand what you ask.
Let's say, in general
You would find the definition of Signal & Background (as it is in BAD
1383) in fittest.C
~azzolini/Semilep01/fitter-24/VirVubFitter/fittest/fittest.C
that is essencially
if(truemodeB==modeB) signal;
if(truemodeB!=modeB) bkg;
while in case you were asking about PDF definition, (again bad 1383) you
can find them in
~azzolini/Semilep01/fitter-24/VirVubFitter/fittest/
files:
ccb.cxx
gauz.cxx
thosig.cxx
but then you need to see
parameters_DATA.txt
parameters_MC.txt
for read which parameters we give to the fit.
Did you do this on R14 or higher?
all the tests done until now have been done on R14.

this is on our plans, we will let you know

great thanks!...sorry for the late reply but i was doing some Gamma-Dalitz
stuffs
ciao ciao
