As data and generic don't change, just link them

chisq comparison for R=0 and R=7.5

Dear all,

As David suggested on the last group meeting, I fitted the single tags
for data with R=0 and R=7.5 respectively. The related plots can be
found at: (Under the section "Single Tag")

http://www.lepp.cornell.edu/~xs32/private/DHad/7.03/plots/

I also made tables comparing their chisq with the regular fits which
has R=15:
(Under section "Comparison" : "chisq")

http://www.lepp.cornell.edu/~xs32/private/DHad/7.03/tables/


The trend looks like what we expected, R=7.5 has closer chisq with
R=15.

For Mode 202, we used the version 7.03 value as initial value

  s1a=new RooRealVar("s1a","s1a",2.25,1.5,4.0);
  f1a=new RooRealVar("f1a","f1a",0.166,0.0,1.0);

Restore the double tag fit code to normal (1.1)

OK.

Message from BES

Thank you for your message. The "r" from the fit is 41+/-458 fm from
the fit mentioned in the paper (hep-ex/0612056). Howevere, the "r"
value from the different fits change a lot. From the fit to the data,
we found that the other parameters are not sensitive to the "r"
value. If we fixed the "r" at a value from several fm to several
thousand fm in the fit, the quantities M_{psi(3770)},
Gamma_{psi(3770)}, Gamma^{ee}_{psi(3770)} and R_{uds} are almost
unchanged.

By the way, Did CLEO-c also make the cross section scan over the
psi(3770) resonance? How may energy points at which CLEO-c collected
the data? And what are the energies?

best regards,

Rong Gang
