NAME

Match - match catalogs by 1D or 2D positions

SYNOPSIS

DESCRIPTION

Match is part of GNU Astronomy Utilities 0.19. Match matches catalogs of objects and (by default) will return the re-arranged matching inputs. The optional log file will return low-level information about the match (indexs and distances).
For more information, please run any of the following commands. In particular the second contains a very comprehensive explanation of Match's invocation: expected input(s), output(s), and a full description of all the options.
All options and their values:
$ astmatch -P
