This is the Category which is illustrated with the largest number of photographs in the present Catalogue. Because of the important relationships which smaller companion galaxies appear to have with respect to their central galaxy (see discussion in the Introduction of Volume I) a large number of candidate associations have been presented here. In some cases there are disturbances or peculiarities in either the companions or the main galaxies which, to some extent, supports the reality of their association. In this respect this Category is closely allied with Category 1: Galaxies with Interacting Companions. In either case the size, or closeness, or number of companions suggests a physical association. Some of these groups have been studied spectroscopically (Arp 1981, 1982) but most remain to be investigated.

8a. Galaxies with Single Apparent Companions

AM 0340-472

These are arranged roughly in order of increasing distance of the companion from the main galaxy, relative to the diameter of the main galaxy. On page 8.1 the companions are very compact (high surface brightness) with narrow, low-surface-brightness rims. In AM 0329-334 small, peculiar spiral arms emerge from the compact centre. The companion in AM 0242-600 is also very compact, and in AM 0124-583 the companion has a very compact core. In AM 1950-585 the companion is itself an M51-type and is also shown in Category 9. This latter object also calls attention to the relationship between Categories 8 and 9. In AM 1129-300 a large, very compact, apparent companion is shown (also shown in Category 13: Compact Galaxies) and in AM 0256-321 a very low-surface-brightness apparent companion is shown.
