In both panels, the red contours show the W3 (12 μm) non-stellar image of NGC 1316 obtained by the scaling method and the yellow contours the inner radio jet (as in Fig. 1). The red contours increase from 2 to 32 μJy/pixel by a factor of two. The substructures agree with those seen in the GALFIT subtraction (Fig. 5) within 1 μJy/pixel, except in the central regions which were oversubtracted by GALFIT. Left panel: non-stellar W3 image in grey-scale. Right panel: HST image in grey-scale. The dashed ellipses show two regions to the NW and SE in which our WISE dust measurements will be compared to the Spitzer measurements (Lanz et al. 2010).
