VII/206             General Photometry of Galaxies        (Prugniel+ 1998)

Total magnitude, radius, color indices, color gradients and photometric type of galaxies Prugniel P., Heraudeau P. <Astron. Astrophys. Suppl. Ser. 128, 299 (1998)> =1998A&AS..128..299P
ADC_Keywords: Galaxy catalogs ; Galaxies, photometry Keywords: galaxies: fundamental parameters - galaxies: general - galaxies: photometry Abstract: The tables presented here give the catalogue of aperture photometry of galaxies (UBVRI), the associated bibliography, the weight and systematic corrections applied to individual datasets. A table give the results of the growth curve fits; the net of curves adopted is a linear interpolation between the de Vaucouleurs (r1/4) and exponential laws. This aperture photometry has three different origins: (i) an update of the catalogue of Buta et al. 1995 (Cat. J/AJ/109/517) (ii) published photometric profiles and (iii) aperture photometry performed on CCD images. Fitting growth curves to aperture photometry of galaxies, in UBVRI, we derive (1) the total magnitude, (2) the effective radius, (3) the color indices and (4) gradients and (5) the photometric type of 5066 galaxies. The photometric type is defined to statistically match the revised morphologic type (numerically coded from -6 to +10) and represents the shape of the growth curve. The catalogue is maintained up-to-date in the database HYPERCAT (http://www-obs.univ-lyon1.fr/~prugniel/cgi-bin/hypercat/). This catalogue supersedes the Longo and de Vaucouleurs (1983) catalogue VII/167. File Summary:

Note on Name: The Name has been adopted by descending the hierarchy: 1) NGC (Cat. VII/118) 2) IC (Cat. VII/118) 3) UGC (Cat. VII/26) or ESO (Cat. VII/34) 4) PGC (Cat. VII/119) Lyon-Meudon Extragalactic Database internal identifier, also acronimed PGC for numbers greater than 73097. The objects left unfolded into this hierarchy are designated as in the original reference, or by their coordinates: Arrrrrrsdddddd. The galaxy identifiers follow the rule already used in Prugniel & Simien 1996 (J/A+A/309/749) and in Prugniel et al. 1998 (J/A+AS/127/117).

Acknowledgements: Philippe Prugniel History: * 17-Feb-2002: Corrected 68 signs of the declination in table4 between -00 and -01 degrees -- all galaxies between -1 and +1 degrees had originally a positive sign (Francois Ochsenbein, CDS). In table4 description, the equinox of the position was erroneously reported as 2000; it was changed to 1950
