FIG. 13. NGC 4108B (a) Contours of constant H I flux overlaid on a greyscale
of the Gunn r optical image of NGC 408-4108B. NGC 4108 is to the south, NGC
4108B is to the north and NGC 4108A is to the west. The H I data are naturally
weighted yielding the synthesized beam shown in the lower right. Contour
levels are logarithmic with levels at 0.04, 0.07, 0.11, 0.19, 0.30, 0.49,
0.79, 1.29, 2.09, 2.39 Jy Bm^-1^ km s^-1^.
