Contour maps of the HIRES processed IRAS maps superimposed on the SOFI Ks band image. The IRAS wavelength is shown in microns in the upper right corner of each panel. The position of the star NX Pup is marked with a filled circle. The IRAS 07178–4429 point source positional uncertainty is shown as an filled ellipse west of NX Pup in the 100 μm panel. The C¹⁸O(2–1) integrated emission contours (indicated by thick lines, 1.2 K   km   s^-1 to 2.0 K   km   s^-1 in steps of 0.4 K   km   s^-1) are superimposed on the 12 μm panel. The offset is in arcminutes from the centre of the SOFI image. The contour levels in MJy sr^-1 are: 12 μm 5 to 30 by 5; 25 μm 15 to 115 by 20; 60 μm 3, 5, 15 to 91 by 19; and 100 μm 7, 16, 31 to 71 by 20.
