Ser. 89 85 1993 1993ApJS...89...85I Photometry, UBV Stars, blue Stars, supergiant catalogs galaxies: individual (M 33) galaxies: stellar content supergiants techniques: photometric We present a catalog of blue and red stars in M33 based on photographic photometry of over 65,000 objects extracted from plates taken with the 3.6m Canada-France-Hawaii Telescope (CFHT) and the 2.0m Rozhen (Bulgarian) Telescope. The completeness limit of the various surveys are estimated here to be V=19.5mag for those stars situated in crowed associations, and V=20.0mag for stars in the interarm fields. We list magnitudes and positions for 2112 blue stars, defined by (U-V)<0.0mag, and V<19.5mag, and 389 red stars defined by (B-V)>1.8mag and V<19.5mag. Of these, 1156 are candidate O stars on the basis of (U-V)<-0.9mag.
