Coverage of the photometric and spectroscopic observations across the Fornax dwarf spheroidal galaxy. The big squares denote the coverage of the CTIO 4 m/MOSAIC fields, while the smaller squares show the CTIO 0.9 m fields. The open (blue) circles show the stars observed in the VLT/FLAMES Ca ii triplet survey (Battaglia et al. 2008; Starkenburg et al. 2010), for which only [Fe/H] is determined. The solid (red) dots mark the stars observed using medium (Kirby et al. 2010) and high resolution spectroscopy (Letarte et al. 2010), for which both [Fe/H] as well as α-element abundances are determined. The dashed (green) ellipse is the tidal radius of Fornax, as given by Battaglia et al. (2006).
