Notes. Photometry 3σ upper limits for the objects with known IR excess not detected by PACS. Only objects with significantly low upper limits (compared to their mid-IR emission) are listed here.


G-85 is a marginal (2.5σ) detection at 160 μm, so we expect that although uncertain, its upper limit to the flux at this wavelength is relatively close to the real value.
