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 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.
