Charm quark mass dependence of the electromagnetic dipole operator   contribution to anti-B -> X(s) gamma at O(alpha**2(s))
  We extend existing calculations of the electromagnetic dipole operator contribution to the total decay rate and the photon energy spectrum of the decay \bar{B} -> X_s\gamma at O(\alpha_s^2) by working out the exact dependence on the charm quark mass.
