Description
Long-slit spectra covering the wavelength range 5000-9500 A have been obtained for three Virgo cluster ellipticals. Measurements of features in the spectra are presented, and their implications are discussed with particular reference to (1) anomalous r-i gradients; (2) ionized gas in the nucleus of NGC 4472; (3) nuclear emission line spectrum of M87; and (4) radial absorption line gradients in NGC 4472 with emphasis on the Na I 8190 A feature. 25 refs
