Abstract:
We present a catalogue of 800 compact radio sources in the declination
range 35deg<δ<75deg whose positions have been measured to an rms
accuracy of ∼12milliarcsec with the VLA. They are primarily intended
for use as phase reference sources for the Jodrell Bank MERLIN but
they will also be suitable phase calibrators for the VLA and the VLBI
networks.

* 15-Jul-1997: Thanks are due to H. Andernach for communicating the
errors he detected, and a corrected position (derived from Taylor et
al's 1996ApJS..107...37T 1996ApJS..107...37T VLA observations) for the source B0256+424
* 11-Nov-1997: further errors reported by Browne et al. to H. Andernach
to be published in "Interferometer phase calibration sources II" for
B1705+456 and B1817+502
