Match - match catalogs by 1D or 2D positions
astmatch [OPTION...] ASTRdata
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.
