Abstract:
We present a catalog and imaging atlas of classical (collisional) RING
galaxies distilled from the Arp-Madore Atlas of Southern Peculiar
Galaxies and Associations and supplemented with other known RING
galaxies from the published literature. The catalog lists the original
host object, compiles available redshifts, and presents newly
determined positions for the central (target) galaxy and its nearest
companion(s). 127 collisional RING systems are illustrated and their
components identified. All of the RINGS have plausible colliders
identified; many are radial-velocity confirmed companions. Finally, we
make note of the existence of a rare subclass of RING galaxies
exemplified by AM 2136-492, double/concentric RING galaxies. These
objects are predicted by numerical simulations, but they appear to be
quite rare and/or short lived in nature.
Description:
All three of the current authors independently inspected and
reclassified each of the 500+ Category 6 (Ring Galaxies) in Arp & Madore
(1987, Cat. VII/170). Only P-type galaxies (on the FMA classification
system) were retained for this study.

Note (1): RA and DE positions measured to a precision of 5 arcsec.
Note (2): S = the separation of the companion from the nucleus of the ring.
--------------------------------------------------------------------------------
Global Notes:
Note (G1): The name of the ring nucleus is composed of the name of the host
object followed by ring nucleus (RN) (e.g., AM 0147-350:RN); by way of
contrast, companion/colliders are identified by the host object name
followed by C1, C2, etc.
* In table 1, components of AM 2100-725 are misprinted:
AM 2056-392:AN instead of AM 2100-725:AN
