EarthAlb:

Path: SC/Environs

% Computes the heat absorbed per unit area due to albedo.
 aF and w can be scalars even if r is not.
--------------------------------------------------------------------------
   Form:
   q = EarthAlb( r, u, uS, alpha, aF, w )
--------------------------------------------------------------------------

   ------
   Inputs
   ------
   r         (:)     Ratio of satellite radius to planet radius
   u         (3,:)   Unit vector to satellite
   uS        (3,1)   Unit vector to sun
   alpha     (1,:)   Absorptivity (should be specific for albedo)*
   aF        (1,:)   Albedo fraction (uses 0.34 if no input)*
   w         (1,:)   Flux (uses 1367 w/m^2 if no input)*
                        *optional

   -------
   Outputs
   -------
   q         (1,:)   Absorbed flux (watts/m^2)
