Abstract:
    We present a catalogue of 800 compact radio sources in the declination
    range 35deg<{delta}<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.

Note (1): P: primary calibrator with >95% of their flux density contained in
              an unresolved component
          S: secondary calibrators up to 20% resolved on the longest
              baselines but with point-dominated structure
          D: double source


History: Prepared via OCR at CDS.
  * 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 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
