Description:
    This catalogue is a compilation of about 5000 stars classified as
    supergiants (class I or II) in the literature. The following
    information is given: DM and HD identifications, coordinates,
    photometry, radial velocity and MK classification

     110  A1     ---     Sep     [/X] Separator ('X' when Sp is from Houk)
 112-127  A16    ---     Sp      Spectral classification (3)

Note (1): The CSI designation (see Ochsenbein et al. 1980) is made of 3 parts:
    the zone, the number, and a code.
    For a positive number, the code indicates which Durchmusterung the
    zone and number refer to:
    - BD (Bonner  Durchmusterung) for  0 ≤ code ≤ 19
    - CD (Cordoba Durchmusterung) for 20 ≤ code ≤ 39
    - CPD (Cape Durchmusterung)   for 40 ≤ code ≤ 59
    A negative number (constructed from 1950 right ascension) is assigned
    for non-DM stars.
Note (2): the quality number (1=poor, 4=good) comes from the UBV catalogue
    by Nicolet (1978);
Note (3): The MK classification from N. Houk (1975, 1978) includes a quality
    from 1 (good) to 4 (poor), a '+' for spectra classified in other sources,
    and 'X' when several spectra were available. When Sep is a '/', the
    classification is from Jaschek (1978)

Historical Notes:
  * June 1980: catalogue prepared and archived at CDS
  * 12-Jul-1995: the catalogue was reformatted at CDS:
    => elimination of record headers "5017A1"
    => creation of a dedicated column for the ':' uncertainty flag u_Vmag
       which was previously embedded in the Vmag column
    => addition of the standard documentation
  * 22-Jul-2000: The minus sign for declinations between 0 and -10
    degrees has been inserted.
