A catalog of IRAS observations of large optical galaxies
Abstract
A catalog is presented of the IRAS observations of 85 galaxies listed in the Second Reference Catalogue of Bright Galaxies with blue-light isophotal diameters greater than 8'. "Total" flux densities at 12, 25, 60, and 100 µm, obtained from spatial maps constructed from co-added IRAS detector data, are reported. Infrared brightness profiles of the detected galaxies and infrared surface brightness contour maps of the galaxies for which structural features were resolved are displayed in an atlas. A far-infrared classification scheme based on the degree of central concentration and spatial structure of the 60 µm emission of the best-resolved galaxies is proposed. The 60 µm and blue-light isophotal diameters of the largest galaxies are compared.
