   FIG. 17. NGC 7677 (a) Contours of constant H I flux overlaid on a greyscale
 of the Gunn r optical image of NGC 7673-7. NGC 7673 is to the west, NGC 7677
 is to the southeast. The H I data is naturally weighted yielding the
 synthesized beam shown in the lower right. Contour levels are logarithmic with
 levels at 0.03, 0.06, 0.10, 0.16, 0.29, 0.50, 0.87, 1.51, 2.63 JY Bm^-1^ km
