Spatial distribution of the populations youngest (top panel) and oldest (bottom panel) than 2.0 Myr (empty circles). Different circle sizes correspond to objects with E(V − I) < 0.5 (smallest circles), 0.5 ≤ E(V − I) < 1.0 (medium circles) and E(V − I) ≥ 1 (largest circles). X symbols indicate objects with mass larger than 2.5 M_⊙. The four regions corresponding to the four VIMOS CCD quadrants are also indicated.
