$\begin{figure} \par\includegraphics[width=8.8cm,clip]{3227f1.ps} \end{figure}$ Figure 1: Gray-scale representation with overlaid isocontours of the background subtracted ISOPHOT ${\rm 60~\mu m}$ map of the region centred on NGC 2293/92. Map pixel size is $25\hbox {$^{\prime \prime }$ }$ . North is up and east to the left. No FIR emission from the galaxy pair is discernible, while the diffuse feature at the western edge might be attributed to NGC 2295.

Map pixel size is $25\hbox {$^{\prime \prime }$ }$ . North is up and east to the left. Weak FIR emission at the position of NGC 2293/92 is detected in the centre of the map, and extended FIR emission from NGC 2295 is present at the western edge.

Map pixel size is $25\hbox {$^{\prime \prime }$ }$ . North is up and east to the left. Strong FIR emission with extension towards south-east and north is detected at the map centre from the galaxy pair NGC 2293/92, while extended and compact FIR emission near NGC 2295 is present at the western edge.

$\begin{figure} \par\includegraphics[width=8.8cm,clip]{3227f4.ps} \end{figure}$ Figure 4: Gray-scale representation with overlaid isocontours of the background subtracted ISOCAM ${\rm 4.5~\mu m}$ map of the region centred on NGC 2293/92. Map pixel size is $5\hbox {$^{\prime \prime }$ }$ . North is up and east to the left. NGC 2293/92 is resolved with extended emission surrounding the compact nuclear regions. A detached arm-like feature lies $\approx$ $100\hbox {$^{\prime \prime }$ }$ south-east of NGC 2293. Most of the unresolved sources in the field are galactic foreground stars.

$\begin{figure} \par\includegraphics[width=8.8cm,clip]{3227f5.ps} \end{figure}$ Figure 5: Gray-scale representation of the optical B-R color image from Barnes (1999) with overlaid isocontours of the ISOPHOT ${\rm 200~\mu m}$ map. Coordinates are B1950. Bluer appears lighter, and redder is darker. The bluer region surrounding the two red galaxies cores can be seen clearly. The peak of the cold dust emission is centred on the galaxy pair. The extended dust emission towards south-east coincides with a significantly redder optical feature.

The dust emission peaks near but slightly south of the hole of the HI ring structure. The extended dust emission towards south-east (cf. 3) coincides with the strongest HI emission.

North is up and east to the left. Map pixel size is $25\hbox {$^{\prime \prime }$ }$ , and $50\hbox {$^{\prime \prime }$ }$ for the upper and lower two maps, respectively. Only at ${\rm 100~\mu m}$ , a weak detection ( ${F_ {100~\rm\mu m} \approx 100~\rm mJy}$ ) is present, while the three other wavelengths only give upper limits of $\approx$ ${\rm 60~mJy}$ .
