This standardized document follows the rules of the Standard Description for Astronomical Catalogues. For those having to work on this catalogue using FORTRAN programs, this ReadMe file can be transformed into a f77-compliant program which reads the files making up this catalogue, in two versions: either a f77 program loading whole files into arrays, or a f77-program reading each data file line by line.

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.

              an unresolved component

              baselines but with point-dominated structure
          D: double source

  * 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
