  A unified Chew-Mandelstam description of single-pion photoproduction data,
together with pion- and eta-hadroproduction data, has been extended to include
measurements carried out over the last decade. We consider photo-decay
amplitudes evaluated at the pole with particular emphasis on ng couplings and
the influence of weighting on our fits. Both energy-dependent and single-energy
analysis (energy-binned data) are considered.
