  Updated values and corresponding uncertainties of Isovector Giant Dipole
Resonance (GDR) parameters which are obtained by the least-squares fitting of
theoretical photoabsorption cross sections to experimental data are presented.
The theoretical photoabsorption cross sections are taken as a sum of the
components corresponding to the excitation of the GDR and quasideuteron
photodisintegration. The current compilation is an extension and improvement of
the earlier compilations of Lorentzian parameters for ground-state photoneutron
and photoabsorption cross sections and covers experimental data made available
up to June 2017.
