Abstract:

We present the results of a 2 & 3mm 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 tex2html_wrap_inline942 with accurate positions (<2tex2html_wrap980), and predicted 3mm flux (based on published low-frequency spectral indices) greater than 300mJy (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 tex2html_wrap_inline948 limits of tex2html_wrap_inline950. 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.
