Table 6: IRAS sources in the MAMBO maps that are not detected as MAMBO emission peaks. For every core in the c2d MAMBO survey the table lists sources from the IRAS Point Source Catalogue and the IRAS Faint Source Catalogue (preceded by an ``F''), and the subcores in which the IRAS sources are located, if applicable. Objects from the IRAS Point Source and Faint Source catalogues present in both catalogues are connected. The last column gives the spectral index between 12 and $25~\rm \mu m$ wavelength.

a Probably an artifact since no corresponding Spitzer source exists.
