Observed (open circles) and dereddened (dots) spectral energy distributions of known YSOs in Cha II detected with the HGBS. The squares mark PACS and SPIRE fluxes, while the dots are optical-to-infrared flux measurements from previous surveys (Alcalá et al. 2008). The Kurucz’s model spectrum (for objects with T_eff ≥ 3500 K) or the blackbody spectrum (for objects with T_eff < 3500 K) with the same T_eff as the object and scaled to its distance and radius (Spezzi et al. 2008), is overplotted on each SED, representing the stellar flux. The red thick line is the best-fitting RADMC-2D SED model, while the gray lines display the first 100 best-fitting SED models.
