SPIRE-250 μm map of Cha II. The continuous and dashed lines highlight the areas previously mapped in the infrared with Spitzer (Alcalá et al. 2008) and in the optical with ESO-2.2.m/WFI (Spezzi et al. 2007), respectively. The squares are the YSOs detected with the HGBS (Table 2). The triangles indicate the position of previously known YSOs not detected with the HGBS (Table 3). The contours from the Spitzer/IRAC extinction map (Alcalá et al. 2008) are also shown.
