Comparison between the flux at 70 μm as measured with PACS and the flux measured with MIPS at the same wavelength for the 23 YSOs in Cha II detected with the HGBS. The solid line and shaded area indicate the median value and the rms of the flux ratio, respectively. The arrow-head line displays the MIPS-70 μm flux range of Cha II YSOs not detected with PACS. The dashed line indicates the PACS-70 μm 5σ detection limit. The clear outlier is Sz 49, the faintest YSO detected with PACS.
