Query: Effective collision strengths for excitation and de-excitation of
  nebular [O III] optical and infrared lines with kappa distributed electron
  energies   We present effective collision strengths for electron excitation and
de-excitation of the ten forbidden transitions between the five lowest energy
levels of the astronomically abundant doubly-ionised oxygen ion, O^{2+}. The
raw collision strength data were obtained from an R-matrix intermediate
coupling calculation using the Breit-Pauli relativistic approximation published
previously by the authors. The effective collision strengths were calculated
with kappa-distributed electron energies and are tabulated as a function of the
electron temperature and kappa.
