New open cluster dataset

Bill J Gray Nov 19, 2003

Hi folks,

Through the efforts of Bertrand Laville and Philippe Laurent,
Guide can now show the "preliminary amateur open cluster catalog"
(PAOCC). This includes assorted objects ranging from "pretty
definitely a real cluster" to "it just _looks_ like a cluster".
See http://www.projectpluto.com/extras.htm#paocc for details.
