TOTAL MAGNITUDE, RADIUS, COLOR INDEXES, COLOR GRADIENTS AND PHOTOMETRIC TYPE OF GALAXIES

We present a catalogue of aperture photometry of galaxies, in UBVRI, a ssembled from three different origins: (i) an update of the catalogue of Buta et al. (1995) (ii) published photometric profiles and (iii) ap erture photometry performed on CCD images. We explored different sets of growth curves to fit these data: (i) The Sersic law, (ii) The net o f growth curves used for the preparation of the RC3 and (iii) A linear interpolation between the de Vaucouleurs (r(1/4)) and exponential law s. Finally we adopted the latter solution. Fitting these growth curves , we derive (1) the total magnitude, (2) the effective radius, (3) the colour indices and (4) gradients and (5) the photometric type of 5169 galaxies. The photometric type is defined to statistically match the revised morphologic type and parametrizes the shape of the growth curv e. It is coded from -9, for very concentrated galaxies, to +10, for di ffuse galaxies.
