A.L.P.O. lunar dark-haloed crater catalog: updated, corrected, and amended.

In the early 1970s, the Lunar Section of the A.L.P.O. conducted a search for lunar dark-haloed craters (DHCs) and in 1976 published a list of them. The 1976 list was incomplete, contained many errors, and was missing the coordinates for several DHCs. In this article, the author has revised, corrected, and amended the original A.L.P.O. DHC catalogue.
