6b. Thin Rings and Centered Nuclei
Starting with page 6.6 we show examples of thin, well defined
rings. The nuclei are only slightly displaced and as the sub-category
proceeds the nuclei became well centered. Objects AM 2020-505 and AM
0226-320 are apparently elongated, one with a thick ring and one with
a thin ring. By page 6.8 the rings are getting thicker and the objects
look more like normal galaxies with circular spiral arms. On pages
6.10 and 6.11 we show some ``bulls-eye'' forms where there are both
inner (usually bright) and outer (usually faint) rings circling a
nucleus. Beyond this point the forms begin to approach closely
