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 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.
