Abstract
We have observed a group of luminous IRAS galaxies in the continuum at 1.25mm with the Caltech Submillimeter Observatory in 1988 May and September. Table I lists the galaxies and their measured flux densities in a 30 beam. The observing conditions for these observations were excellent and stable. Uranus was the fundamental flux density calibrator, it was assumed to have a brightness temperature of 100 K at 1.25 mm (Hildebrand et al. 1985; Ulich 1974). Integration times were typically a half hour per night, repeated for a total of two or three nights. The bolometer NEFD is 0.5 Jy Hz^(-1/2) giving statistical errors of 8 to 12 mJy. Systematic uncertainties have not been included in the error estimates, but we believe that they are small, at most 20%.
