I_obh

Calculates the solar beam energy on a horizontal surface at the top of the Martian atmosphere
(before atmospheric attenuation) between specified start and end times. Implements Equation 11
from Appelbaum &amp; Flood (1990).

A set of functions to calculate solar irradiance and insolation on Mars horizontal and inclined surfaces. Based on NASA Technical Memoranda 102299, 103623, 105216, 106321, and 106700, i.e. the canonical Mars solar radiation papers.
