Astro::Cosmology - calculate cosmological distances, volumes, and times
This module provides a set of routines to calculate a number of cosmological quantities based on distance and time. Some are a bit complex - e.g. the volume element at a given redshift - while some, such as the conversion between flux and luminosity,...DJBURKE/Astro-Cosmology-0.90 - 04 Aug 2001 15:53:34 UTC
Astro::Constants - This library provides physical constants for use in Physics and Astronomy based on values from 2018 CODATA.
This module provides physical and mathematical constants for use in Astronomy and Astrophysics. The values are stored in Physical_Constants.xml in the data directory and are mostly based on the 2018 CODATA values from NIST.
