J/A+A/453/493 Line-strength indices in IC 4200 (Serra+, 2006) ================================================================================ IC 4200: a gas-rich early-type galaxy formed via a major merger. Serra P., Trager S.C., Van der Hulst J.M., Oosterloo T.A., Morganti R. =2006A&A...453..493S ================================================================================ ADC_Keywords: Galaxies, spectra ; Velocity dispersion ; Abundances Keywords: galaxies: elliptical and lenticular, cD - galaxies: evolution - galaxies: interactions - galaxies: stellar content - galaxies: formation - galaxies: peculiar Description: Optical spectroscopy, imaging and radio observations of the galaxy IC 4200 are analysed in order to determine the formation history of the galaxy. The two tables available contain informations extracted from the long-slit spectra of IC 4200. The spectra were taken with ESO/NTT/EMMI mounted on the NTT on 12 July 2004, as described in Sec. 3.2 and in Table 4 of the paper. tablec1.dat contains informations on the stellar and ionised-gas kinematics along the optical major and minor axis of the galaxy. The stellar kinematics was determined by fitting Bruzual & Charlot (2003MNRAS.344.1000B) stellar populations synthesis models to the low-S/N 1D bins extracted from the 2D spectrum of IC 4200 (Sec. 3.2.1). The kinematics of the ionised gas was determined by fitting single Gaussians to the Halpha emission line; for this purpose we used IRAF.NOAO.ONEDSPEC.SPLOT. tablec2.dat contains the values of the Lick/IDS indices measured along the optical major and minor axis of IC 4200. The values given are corrected for the effect of velocity dispersion and shifted to the Lick/IDS system.
