% Computes the flux from a flat plate.
Assumes a single sided Lambertian radiator. Includes eclipses.
This function assumes that the spacecraft are in earth orbit.
The function does not handle blockage from the earth since the distance
would be too great for any flux to reach the spacecraft from the
target.
Type SolarFluxFromPlateECI for a demo of two spacecraft about 7 km
apart. The camera in the demo points at the target and the flat
plate points at the camera. The flate plate is in a slightly
elliptical orbit.
