Image Details
Caption: Figure 2.
Comparison of the original resolution-enhanced WISE 22 μm image (first column) and the same image convolved to 15″ (second column) using the transformation kernel from G. Aniano et al. (2011) for two example galaxies, NGC 3044 (top row) and NGC 660 (bottom row). Note that the ring around NGC 660 is an artifact and does not trace the polar ring of this galaxy. To highlight this artifact, in the third panel of the second row we show an extracted profile that starts at the galaxy’s center (indicated in the second panel of the second row). The PSF size is indicated as a black circle in the lower left corner for the images and as a black line in the lower right corner for the profile.
