Hi,
I implemented the possibility to use a finer binning in q2 beyond 14
GeV^2/c^4 in VirVubFitter. The q2 background subtracted plot now looks
like:
www.slac.stanford.edu/~petrella/q2bkgsub.eps
Using the fitter with finer q2 binning we have no significant
differences with respect to the old version with a single bin beyond 14,
as you can see from the numbers below:
WIDER BINNING FINER BINNING
Data 1'bin 608.474+-31.8388 607.88+-31.7538
Chi square of the fit 0.762561 0.773425
PBRBR 0.00793253+-0.000868 0.00797426+-0.000884
You can use your favourite q2 binning by using the tag ap-062905 and the
flag -q2V <filename> where filename contains the bin boundaries.
Have a nice day,
Antonio
