Description:
    An objective prism survey was conducted to discover probable members
    of the Small Magellanic Cloud. Interference filters were used to
    restrict the wavelength range and, hence, decrease the background and
    crowding. The limiting absolute magnitude of the survey is about -4.5.
    The 1975 paper listed 506 stars that show high luminosity
    characteristics; 193 of them had been confirmed by other authors. The
    1979 paper added 14 additional probable members and photometric
    observations of 11 stars from the earlier paper that confirmed their
    membership. For completeness, four new Wolf-Rayet stars detected by
    Azzopardi and Breysacher (1979) were included.

    The catalog contains a catalog number in order of right ascension with
    the suffixes "a" or "b" used for the newer stars interpolated in the
    original list. Also included are the 1975 position, the MK spectral
    classification, the V magnitude, the (B-V) and (U-B) color indices,
    the number of observations, the identification chart number, and
    remarks indicating previous identifications.

    A later catalogue of the Small Magellanic Could star members
    is also published by Azzopardi and Vigneau  =1982A&AS...50..291A

Nomenclature Note:
    The stars from this paper (and the 1982 one) are found in the
    literature with several designations: AzV, AV, AZ, AZO, or AzVi.
