Abstract

We present a catalogue of 540 compact radio sources in the declination ranges +20 ≤ δB1950 ≤+35° and +75 ≤ δB1950 ≤+90°, the positions of which have been measured to an rms accuracy of about 55 mas with the Very Large Array (VLA). These sources are primarily intended for use as phase calibration sources for MERLIN. However, they will also be suitable as phase calibrators for the VLA and can be considered as candidate phase calibrators for very long baseline interferometry (VLBI) networks.
