Optimized Spectral Energy Distribution for Seyfert Galaxies

The temperature predicted by photoionization models for the Narrow Line Region of Seyfert 2 galaxies is lower than the value inferred from the observed [O III] {\lambda}4363A/{\lambda}5007A line ratio. We explore the possibility of considering a harder ionizing continuum than typically assumed. The spectral ionizing energy distribution, which can generate the observed {\lambda}4363A/{\lambda}5007A ratio, is characterized by a secondary continuum peak at 200 eV.Comment: 17 pages, 4 figures, accepted for publication in Revista Mexicana de Astronom\'ia y Astrof\'isic
