Query: Derived Born cross sections of $e^+e^-$ annihilation into open charm
  mesons from CLEO-c measurements   The exclusive Born cross sections of the production of $D^0$, $D^+$ and
$D_s^+$ mesons in $e^+e^-$ annihilation at 13 energy points between 3.970 and
4.260 GeV are obtained by applying corrections for initial state radiation and
vacuum polarization to the observed cross sections measured by CLEO-c
experiment. Both the statistical and the systematic uncertainties for the
obtained Born cross sections are properly estimated.
