PlotSailForce2D:

--------------------------------------------------------------------------
   Plot relationship between force, normal, and sun vectors in 2D
   Clarifies the centerline angle, the angle between the sail normal and
   the resulting force vector. This angle is nonzero for sails with
   nonideal optical properties, i.e. a diffuse component to the reflected
   radiation.

   Since version 7.
