HIRES‐processed IRAS images after 20 iterations. Upper left: At 12 μm, ﹩5< I< 10^{4}﹩ MJy sr⁻¹; upper right: at 25 μm, ﹩5< I< 10^{4}﹩ MJy sr⁻¹; lower left: at 60 μm, ﹩25< I< 10^{4}﹩ MJy sr⁻¹; and lower right: at 100 μm, ﹩10^{2}< I< 10^{4}﹩ MJy sr⁻¹. Ellipses show the areas over which the images were integrated to obtain fluxes, as explained in the text. Data inside the contours have negative values, indicated by the tick marks in the 60 and 100 μm images. Ringing artifacts from the HIRES processing can be seen around the bright cores, especially at 60 and 100 μm.
