INTERFEROMETER PHASE CALIBRATION SOURCES - II - THE REGION L-TO-DELTA(B1950)LESS-THAN-OR-EQUAL-TO-DEGREES(20)

We present a catalogue of 781 compact radio sources in the declination range 0 degrees less than or equal to delta(B1950) less than or equal to +20 degrees whose positions have been measured to an rms accuracy of about 14 mas with the Very Large Array (VLA). These sources are pri marily intended for use as phase calibration sources for the Jodrell B ank MERLIN. However, they will also be suitable as phase calibrators f or the VLA and can be considered as candidate phase calibrators for Ve ry long-baseline interferometry (VLBI) networks.
