Galaxy spectra, colors and line strengths. Pickles, A. J. ; Visvanathan, N. Abstract Flux-calibrated spectra are presented for the nuclei of 12 elliptical and five lenticular galaxies in the Fornax Cluster (V0 = 1430 km/s). The continuous spectra have a resolution of 10-20 A and wavelength coverage extending from 3600 A to a maximum of 10,000 A. The galaxies have been selected to cover a large range (of about 6 mag) of absolute magnitude and provide a good, representative sample defining the color-magnitude diagram for the Fornax Cluster. Spectrophotometric colors derived on the Kron-Cousins UBVRI system are compared with published photoelectric photometry, and the variation with nuclear luminosity of several prominent line strengths is discussed.
