The Age-Metallicity Relation of stars on the upper RGB in the Fornax dSph, incorporating the full SFH and MDF information. Medium and high resolution spectroscopy from Letarte et al. (2010); Kirby et al. (2010) is shown as blue points, while Ca ii triplet spectroscopy from Battaglia et al. (2008) is shown in red. The AMR of the Sculptor dSph, from HR spectroscopy, is shown as green points (de Boer et al. 2012).
