Morphology of the 12 micron Seyfert galaxies. II. Optical and near-infrared image atlas

We present 263 optical and near-infrared (NIR) images for 42 1s and 48 Seyf ert 2s, selected from the Extended 12 mu m Galaxy Sample. Elliptically aver aged profiles are derived from the images, and isophotal radii and magnitud es are calculated from these. We also report virtual aperture photometry th at, judging from comparison with previous work, is accurate to roughly 0.05 mag in the optical, and 0.07 mag in the NIR. Our B-band isophotal magnitud e and radii, obtained from ellipse fitting, are in good agreement with thos e of Third Reference Catalogue of Bright Galaxies. When compared with the B band, V, I, J, and K isophotal diameters show that the colors in the outer regions of Seyfert galaxies are consistent with the colors of normal spira ls. Differences in the integrated isophotal colors and comparison with a si mple model show that the active nucleus + bulge are stronger and redder in the NIR than in the optical. Finally, roughly estimated Seyfert disk surfac e brightnesses are significantly brighter in B and K than those in normal s pirals of similar morphological type.
