Abstract:
We present a multi-waveband analysis of a 126-galaxy sub-sample of the
12um galaxy sample (12MGS), for which we have carried out a detailed
X-ray spectral analysis in a previous paper. We determine the activity
class of the galaxies by way of optical-line ratio diagnostics and
characterize the optical classes by their X-ray, 12um and [OIII]
luminosities and X-ray spectral properties.
Description:
We have obtained narrow-line ratios from a compilation of unpublished
data from Rodriguez et al. (in preparation) for 70 of the galaxies in
our sample of 126 sources. For the rest, where they exist, we have
compiled from the literature the [OIII]/Hβ, [OI]/Hα,
[NII]/Hα and [SII]/Hα line ratios which are needed for
this classification method. In five cases we have used SDSS DR7
emission-line data, where no literature line ratio data exist.
