Query: Muon and Muon Neutrino Fluxes from Atmospheric Charm   The charm contribution to the atmospheric fluxes of muons and muon neutrinos
may be enhanced by as much as a factor of 10 when one includes the
contributions of D->pi,K->leptons and folds in uncertainties in the charm cross
section and energy distribution. In the energy range considered here, from 100
GeV to 10 TeV, the charm contribution is small compared to the conventional
flux of muons and muon neutrinos.
