% Solar flux variation over Earth orbit. Model the Earth orbit around the sun for a year and call SolarFlx, to demonstrate the variation in solar flux, which is nearly 100 W/m2. The reported flux is the flux above the atmosphere. The same scaling law is used by TerrestrialSolarFlux, which also returns the sun unit vector in the Earth-centered (ECI) frame, but using the Almanac function SunV1 to compute the sun vector instead of PlanetPosition. The results are therefore slightly different. ------------------------------------------------------------------------- See also SolarFlx, PlanetPosition, Constant, Plot2D, Date2JD, Mag, TerrestrialSolarFlux -------------------------------------------------------------------------
