Maps of 15  ×  15 of B1-bS and B1-bN at all wavelengths, with sizes and positions derived from the Gaussian fits. The FWHM of the respective instrumental beam is shown as a circle in the bottom-left corner of each respective panel. At λ ≤ 100 μm, the source S295 is also visible. Colour bars are in Jy/beam for the SCUBA maps, and MJy/sr in all the others. In the Spitzer images, positions and sizes of the sources are copied from the 70 μm map. IRAC maps are in the top row, from left to right: a) 3.8 μm; b) 4.5 μm; c) 5.8 μm; d) 8.0 μm. Second row: e) Spitzer 24 μm; f) PACS 70 μm, B1-bN is not really detected and its flux corresponds to a 1σ rms point source; g) PACS 100 μm; h) PACS 160 μm, S295 is no longer visible. Third row: i) SPIRE 250 μm; j) SPIRE 350 μm; k) SCUBA 450 μm, where the beam shown is 11′′, see Appendix A.2; l) SPIRE 500 μm. Bottom row: m) SCUBA 850 μm; n) Bolocam 1.1 mm, where only one source has been fitted.
