The Palomar Compact Galaxy Catalogue

The Palomar Compact Galaxy Catalogue - A select sampling of 60 of 459 compact groups. This list was created by Dr. Angela Iovino of Italy, using a similar selection criteria as Hickson, Shakhbazian, and Rose in their respective projects. The criteria is a bit tighter and uses an automated algorithim scanning POSS plates > 40 degrees from the galactic equator. This list is the ultimate compact galaxy list. All of them are less than a arc minute. Think about it, 1 arc minute is 60 arc seconds, meaning that many entire Palomar Compact Galaxy group would be covered by Jupiter! (70+ pages)
