Scientific paper

We present the results of a 2 & 3 mm Swedish--ESO Submillimetre Telescope continuum survey of bright southern flat--spectrum radio sources. Our sample consists of all sources in the PKSCAT90 catalog south of declination -40 deg with accurate positions (<2 arcsec), and predicted 3 mm flux (based on published low--frequency spectral indices) greater than 300 mJy (47 sources). In addition, 32 bright radio sources from the USNO Radio-Optical Reference Frame catalog have been observed. Our overall detection rate for the combined sample is 66% above typical 5 sigma limits of 300-500 mJy. This survey has identified many new sources suitable for use as phase and pointing calibrators for southern millimeter interferometers. A number of individual sources are discussed.
