Query: Problems with Extraction of the Nucleon to Delta(1232) Photonic
  Amplitudes   We investigate the model dependence and the importance of choice of database
in extracting the {\it physical} nucleon-Delta(1232) electromagnetic transition
amplitudes, of interest to QCD and baryon structure, from the pion
photoproduction observables. The model dependence is found to be much smaller
than the range of values obtained when different datasets are fitted. In
addition, some inconsistencies in the current database are discovered, and
their affect on the extracted transition amplitudes is discussed.
