Match - match catalogs by 1D or 2D positions
astmatch [OPTION...] ASTRdata
Match is part of GNU Astronomy Utilities 0.14. 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).
