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 with
accurate positions (
), 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
limits of
. 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.
