astcosmiccal [ OPTION...]


CosmicCalculator is part of GNU Astronomy Utilities 0.4. CosmicCalculator will do cosmological calculations.
For more information, please run any of the following commands. In particular the second contains a very comprehensive explanation of CosmicCalculator's invocation: expected input(s), output(s), and a full description of all the options.
All options and their values:
$ astcosmiccal -P
Inputs/Outputs and options:
$ info astcosmiccal
Full section in manual/book:
$ info CosmicCalculator
Full Gnuastro manual/book:
$ info gnuastro
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
