cds-question@unistra.frgalaxiesvisible-astronomytwo-color-diagramsTotal color indices (V-R)tot, (V-I)tot and effective color indices (V-R)eff, (V-I)eff 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.1995AJ....109..543Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/109/543CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/109/543https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/109/543http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/109/543https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/109/543https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/109/543http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/109/543GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/AJ/109/543/table5Total and effective V-R and V-I color indices for 501 galaxiesrecnoRecord number assigned by the VizieR team.
