.SH NAME
CosmicCalculator \- estimate cosmological values
.SH SYNOPSIS
.B astcosmiccal
[\fI\,OPTION\/\fR...]
.SH DESCRIPTION
CosmicCalculator is part of GNU Astronomy Utilities 0.8.
CosmicCalculator 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.
.PP
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.
