Notes.

(a)

sym = symmetric, asym = asymmetric.

(b)

A number given denotes the number of connection points of the molecular ring to dust lanes, “–” indicates that there is no information available on a possible ring-dust lane connection.

(c)

A number given denotes the number of GMAs found in the molecular rings and dust lanes, “–” indicates that there is no information available on GMAs in these objects.

(d)

Part of an interacting galaxy pair with IC 5283.

(e)

Part of an interacting galaxy pair with M 81.
