Left: at 70 μm with PACS, the binary α Cen AB is clearly resolved (Hi-GAL data). As a result of the re-binning using cubic spline interpolation, the stars appear too close in this image. Right: the method for the estimation of the source and background fluxes in the SPIRE images is illustrated. Shown is a cut in right ascension through the image, normalised to the interstellar dust feature 40′′ east of α Cen. For comparison, the 160 μm PACS data are also shown in blue. For SPIRE, green identifies 250 μm, red 350 μm, and black 500 μm.
