Query: Quark-mass and $1/N_c$ corrections to the vector-meson
  pseudoscalar-meson photon ($VP\gamma$) interaction   We analyze quark-mass and $1/N_c$ corrections to all of the radiative
transitions between the vector-meson nonet and the pseudoscalar-meson nonet
within a chiral effective Lagrangian approach. We perform fits of the available
coupling constants to experimental data and discuss the corresponding
approximations. In terms of five (six) coupling constants, we obtain a
reasonably good description of the 12 experimental decay rates.
