Notes. The four rows denoted as IRACi report the 1σ upper limits derived on the maps at the positions of the sources at 160 μm. Size is the instrumental FWHM. The row denoted as MIPS1 reports the 5σ upper limit at 24 μm, found by analyzing the Spitzer map with DAOPHOT inside an aperture of 12′′. For all the other wavelengths, the fluxes were measured by fitting a 2D Gaussian at the positions found by CuTEx. Size is the FWHM of the elliptical Gaussian fitted to each source, circularized and deconvolved with the instrument beam size. The 70 μm flux of B1-bN is equal to that of a point source having a 1σ rms peak flux, so we consider it as an upper limit. The 160 μm data are from the map scanned at 20′′/s. The uncertainties were estimated as the differences in the fluxes extracted with two independent methods: CuTEx and getsources (Men’shchikov et al. 2012). Herschel fluxes have had Gaussian fit corrections applied but no colour corrections, see Appendix A.1.
Enoch et al. (2006): 2.61 Jy within 53′′ × 59′′.
