Daily Insolation over Latitude
- Author: O.Conrad (c) 2012

Description
Orbital parameters used here are based on the work of Andre L. Berger and its implementation from the NASA Goddard Institute for Space Studies (GISS). Berger's orbital parameters are considered to be valid for approximately 1 million years.
