1995AJ....109..543B TOTAL-AND EFFECTIVE COLORS OF 501 GALAXIES IN THE COUSINS VRI PHOTOMETRIC SYSTEM R. BUTA University of Alabama, Tuscaloosa, Alabama 35487-0324 Electronic mail: buta@sarah.astr.ua.edu KESHA L. WILLIAMS Jackson State University, Jackson, Mississippi 39217-0460 Received 1994 September 9; revised 1994 October 25 ABSTRACT Total color indices (V - R)_T_, (V - I)_T_ and effective color indices (V - R)_e_, (V - I)_e_ in the Cousins VRI photometric system are presented for 501 mostly normal galaxies. The colors are computed using a procedure outlined in the Third Reference Catalogue of Bright Galaxies (RC3) whereby standard color curves approximated by Laplace-Gauss integrals are fitted to observed photoelectric multiaperture photometry. 11 sources of such photometry were used for our analysis, each source being assigned an appropriate weight according to a rigorous analysis of residuals of the data from the best-fitting standard color curves. Together with the integrated B - V and U - B colors provided in RC3, our analysis widens the range of wavelength of homogeneously defined colors of normal galaxies of all Hubble types. We present color-color and color- type relations that can be modeled to understand the star formation history of galaxies.
