NAME
       CosmicCalculator	- estimate cosmological	values

SYNOPSIS
       astcosmiccal [OPTION...]

DESCRIPTION
       CosmicCalculator	is part	of GNU Astronomy Utilities 0.12.  CosmicCalcu-
       lator will do cosmological calculations.	If no redshfit	is  specified,
       it  will	 only  print  the main input parameters. If only a redshift is
       given, it will print a table of all calculations. If any	of the	single
       row  calculations are requested,	only their values will be printed with
       a single	space between each.

       For more	information, please run	any of the following commands. In par-
       ticular the second contains a very comprehensive	explanation of Cosmic-
       Calculator's invocation:	expected input(s), output(s), and a  full  de-
       scription 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
