The catalogue reports the observations of 85 galaxies listed in RC2 with apparent blue light isophotal diameters (D25) greater than 8'; there are 83 corresponding maps (NGC 205 and M31 are in one field as are M81 and M82) listed in file "summary". The surface brightness maps have been written to tape in FITS format, as 83 sets of maps, each set consisting of an image and a noise map for each of the four IRAS wavelength bands, leading to 664 FITS images.
