摘要：

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 degrees with accurate positions (< 2 ''), 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 typ ical 5 sigma limits of 300 - 500 mJy. This survey has identified many new sources suitable for use as phase and pointing calibrators for southers millimeter interferometers. A number of individual sources are discussed.
