Description:
    The purpose of the present work is to provide a complete list of MK
    standard stars, selected from the main papers related to this subject,
    according to the recommendations of both authors of the MK system.
    The catalogue provides a list of 963 standard stars, with their
    spectral type, luminosity, equatorial coordinates, magnitudes, colour
    index (B-V), and references.
    The magnitude and colours were taken from Mermillod (1986) UBV
    Photoelectric Photometry Catalogue (catalog II/122).
    In the cases without observations with the UBV catalogue, the
    apparent magnitude was taken from the SIMBAD data-base
    (SIMBAD is described at http://cdsweb.u-strasbg.fr/Simbad.html)

Historical Notes:
  * The original version contained two more tables with the same data
    sorted by right ascension and by declination. These additional
    tables can easily be recreated by any sort utility.
  * 16-Feb-1996: coordinates were originally written in several
    formats; the u_RAs and u_DEs columns have been introduced when
    tenths of (arc)minutes were converted into (arc)seconds at CDS.
