The Cartwheel: a) Contour map of the ISOCAM LW2 emission overlayed on a HST wide I band image. The contour levels are from 0.1 to 0.5 mJy/pixel with a step of 0.05 mJy/pixel. b) Contour map of the ISOCAM LW3 emission overlayed on the same HST image. The contour levels are 0.2, 0.3, 0.4, 0.6, 0.8, 1, 1.2 and 1.4 mJy/pixel. North is up and East is left in both images.

These results have been discussed in the paper:

"Mid-IR Imaging of Collisional Ring Galaxies with ISOCAM", V. Charmandaris and al., 1998 presented at the conference: "The Universe as seen by ISO" (Proceedings: ESA SP-427).
