Usage

Overview

Match is part of GNU Astronomy Utilities 0.23. 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.

If you couldn't find your answer in the manual, you can get direct help from experienced Gnuastro users and developers. For more information, please run:

$ info help-gnuastro
