Comment on: "Vortex-assisted photon count and their magnetic field   dependence in single-photon superconducting detectors" by L.N. Bulaevskii,   M.J. Graf and V.G. Kogan, Phys. Rev. B 85, 014505 (2012)
  In this Comment we show that the statements made in PRB85, 014505 (2012) regarding our work (PRL 100, 227007 (2008))) are incorrect because they result from model artifacts. We address the issues neglected in PRB85, 014505 (2012) and discuss their importance for a more consistent theory of thermally-activated hoping of vortices in thin films and the interpretation of experimental data.
