I_bh

Calculates the direct beam solar energy received on a horizontal surface between specified
start and end times. Implements Equation 19 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.
