1991A&AS...88..325W CCD surface photometry of early-type barred galaxies. I. Data reduction and results H. Wozniak and M.J. Pierce Observatoire de Marseille, 2, Place Le Verrier, F-13248 Marseille Cedex 04, France Dominion Astrophysical Observatory, Herzberg Institute of Astrophysics, National Research Council of Canada, 5071 West Saanich road, Victoria B.C., V8X4M6, Canada Received September 14; accepted November 9,1990 Abstract. - We present the results of detailed CCD surface photometry of a sample of ten early-type barred galaxies. It is a part of a sample of early-type galaxies which forms the data base of a series of papers dealing with morphological and dynamical properties of bars and ovals. The observations were made in three colors (B Johnson, I and R Kron-Cousins bandpasses). We display surface brightness, ellipticity and position-angle profiles for each galaxy, obtained by fitting ellipses to the isophotes. Various parameters, like bar length, angle of inclination on the plane of the sky, etc..., are determined. We also discuss the accuracy of ellipse- fitting in the bar region where the isophotes are more rectangular than they are in elliptical galaxies. Key words: data analysis - galaxies: barred - galaxies: lenticular - photometry - galaxies: NGC 936, NGC 1326, NGC 4251, NGC 4371, NGC 4442, NGC 4477, NGC 4479, NGC 4596, NGC 4608.
