Hello,
Mes fits for run 1,2,3 and 4 for the B->D*pi (D*->Dpi) modes can be found
in
http://www.slac.stanford.edu/~henning/plots/
mean of Gauss in CB fit
run1 5.27995 +- 0.00005
run2 5.28002 +- 0.00003
run3 5.27987 +- 0.00004
run4 5.27956 +- 0.00003
Generally, our mean values are lower than those reported by David, but the
mean for the gaussian in the crystal ball fit for run 4 is also somewhat
lower (0.3-0.4 keV).
In the above place are also plots for deltaE for the same data sample and
run periods. There is no obvious difference in the mean and rms for the
different run periods though.
Cheers,
Henning & Clare
