Abstract

An analysis of Coronal Lines (CLs) emitted in the near IR (0.8 a 2.3mum) is presented for a sample of 54 active galaxies. It is found that CLs are prone to appear more in Type 2 galaxies than in Type 1. The existence of some energetic CLs almost in equal percentage for both type of objects could indicate that the inner face of the torus is not a strong emission region of CLs. It is observed that the majority of NLS1 galaxies tend to present a correlation between the FWHM and the ionization potential; however that correlation holds in less than half of the Type 2 and ``Normal'' Type 1 galaxies. Finally, it is also observed a weak correlation between the soft X-ray luminosity (0.1-2.4 keV) and the luminosity of the most conspicuous CLs.
