a) Spatial Hess−like diagram of BP stars in the Fornax dSph. The two dashed circles indicate the position of two over-densities, one known and one new. b) The spatial distribution of BP stars in the region corresponding to both detected over-densities. Dashed (black) boxes indicate the area selected for each over-density. The (green) ellipse shows the annulus corresponding to a radius of r_ell = 0.3 degrees from the centre of Fornax, assuming the structural parameters from Irwin & Hatzidimitriou (1995).
