This paper provides the full details of the analysis and estimates of internal and external errors in the parameters. The derivation of the parameters is based on techniques described by de Vaucouleurs & Corwin [ApJS, 33, 219 (1977)] whereby photoelectric multiaperture data are fitted by mean Hubble-type-dependent curves which describe the integral of the B-band flux and the typical B-V and U-B integrated color gradients. A sophisticated analysis of the residuals of these measurements from the curves was made to allow for the random and systematic errors that affect such data. The result is a homogeneous set of total magnitudes BAT, total colors (B-V)T and (U-B)T, and effective colors (B-V)e and (U-B)e for more than 3000 bright galaxies in RC3.Item MEAN MORPHOLOGICAL TYPES OF BRIGHT GALAXIES(American Institute of Physics, 1994-01) Buta, R; Mitra, S; Devaucouleurs, G; Corwin, HG; University of Texas System; University of Texas Austin; California Institute of Technology; University of Alabama TuscaloosaThe revised Hubble classifications provided in the Third Reference Catalogue of Bright Galaxies are based on nine lists and catalogues, both published and unpublished, from five observers. This paper describes the procedures that were used to combine these classifications into mean classifications including the family, variety, and stage. The best classifications in RC3 are based on large-scale photographic images taken with 1.5-5 m class reflectors. However, most of the types in RC3 are based on the small-scale prints, plates, and films of the first Palomar Sky Survey and the UK Schmidt IIIa-J Southern Sky Survey. The overlap between the different observers' samples allowed determination of the reliability of sky survey types and the effects of diameter and inclination on the accuracy of these types. We find that for a typical galaxy having isophotal diameter D25 almost-equal-to 2' and inclined by almost-equal-to 50-degrees, types T from the sky surveys have a mean error (averaged over all of the observers) of sigma(T)=0.7 step on the numerical scale of the revised Hubble system. With the new database of classifications, we rederive the classical relations between Hubble type and integrated colors, surface brightnesses, and hydrogen index (hydrogen flux to blue light ratio) for a large sample of galaxies. We also present a table of galaxies which we consider to be representative examples of each type.
