   FIG. 15. NGC 5394 (a) Contours of constant H I flux overlaid on a greyscale
 of the Gunn  r optical image of NGC 5394-5. NGC 5394 is the face on galaxy to
 northwest and NGC 5395 is the large galaxy to the southeast. The H I data are
 naturally weighted yielding the synthesized beam shown in the lower right.
 Contour levels are logarithmic with levels at O.11, 0.17, 0.26, 0.39, 0.60,
 0.91, 1.33, 2.10, 3.20, 4.87 Jy Bm^-1^ km s^-1^.
