2006A&A...445...79A Nearby early-type galaxies with ionized gas II. Line-strength indices for 18 additional galaxies F. Annibali, A. Bressan, R. Rampazzo and W. W. Zeilinger Received 4 July 2005 / Accepted 4 August 2005 We previously presented a data-set of line-strength indices for 50 early-type galaxies in the nearby Universe. The galaxy sample is biased toward galaxies showing emission lines, located in environments corresponding to a broad range of local galaxy densities, although predominantly in low density environments. The present addendum enlarges the above data-set of line-strength indices by analyzing 18 additional early-type galaxies (three galaxies, NGC 3607, NGC 5077 and NGC 5898 were presented in the previous set). We measured 25 line-strength indices, defined by the Lick IDS "standard" system (Trager et al. 1998, ApJS, 116, 1; Worthey & Ottaviani 1997, ApJS, 111, 377), for 7 luminosity weighted apertures and 4 gradients of each galaxy. This addendum presents the line-strength data-set and compares it with the available data in the literature. Key words: galaxies: elliptical and lenticular, cD, galaxies: fundamental parameters, galaxies: formation, galaxies: evolution
