Scientific paper

Abundances of high metallicity (low excitation) H II regions are difficult to derive, as the temperature sensitive λ4363 Å line is very weak or absent in these objects. Empirical methods using strong emission lines covering a wide spectral range (λ3700 to λ9600 Å) combined with photoionization models provide reliable abundances for these objects.
