   FIG 19. NGC 7769 (a) Contours of constant H I flux overlaid on a greyscale
 of the Gunn r optical image of NGC 7769-71. NGC 7769 is to the face on galaxy
 to the west. NGC 7771 is the largest of the galaxies to the east. The H I data
 are naturally weighted yielding the synthesized beam shown in the lower right.
 Contour levels are logarithmic with levels at O.04, 0.06, 0.11, 0.18, 0.30,
 0.50, 0.83, 1.37, 2.28 Jy Bm^-1^ km s^-1^ .
