Left panel: overlay of the CO(2–1) intensity contours (levels as in the left-hand panel of Fig. 12) on the HST optical image of IRAS 17208-0014 obtained in the F814W band (color scale as shown in arbitrary units). Middle panel: same as left panel but with CO contours overlaid on the HST image obtained with NICMOS in the F160W band (color scale as shown in arbitrary units). Right panel: same as middle panel but zooming in on the continuum emission image of IRAS 17208-0014 at 221.1 GHz, in contours (1%, 2%, 5%, 10%, to 90% in steps of 10% of the peak value = 30.4 mJy beam^-1 ~ 250σ), overlaid on the HST NICMOS image. The filled ellipses represent the CO beam size.
