Central region of the Antlia cluster of galaxies. Upper panel: DSS image in the R filter of a region containing the gEs NGC 3258 and NGC 3268, with a FoV of 30 × 30 arcmin2. The FoVs of the two ACS fields are marked with red and blue polygons. Both cEs analysed in this article, FS90 110 and FS90 192, are highlighted with circles. Lower panels: F814W images for the two ACS fields, including the Gemini-GMOS slits used for the spectroscopic analysis. The three images follow the usual orientation: north is up and east to the left.
