Abstract

We present a catalog of 321 compact radio sources in the declination range 0° > δ > -30°. The positions of these sources have been measured with a two-dimensional rms accuracy of 35 milliarcseconds using the NRAO6 Very Large Array. Each source has a peak flux density >50 mJy at 8.4 GHz. We intend for this catalog to be used mainly for selection of phase calibration sources for radio interferometers, although compact radio sources have other scientific uses.
