H_bi

Calculates the direct beam solar energy received over a full Martian day on an inclined surface.
Obtained by integrating beam irradiance from sunrise to sunset.

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.
