CompareSailOptical:

% Compare the solar pressure force for ideal and nonideal circular sails.
   Compare an ideal, perfectly specular sail with CP1 material (about 90% specular) 
   and two other fictional materials. Also computes the temperature, but
   note that the temperature is not defined for the perfect sail since it
   depends on the absorption coefficient being nonzero.

   Since version 7.
