SunNadir:

Path: SC/Ephem

% Compute the sun-nadir angles and yaw rate. 
   The sun is defined in a coordinate frame with the orbit in the xy-plane and 
   z along the +normal. The sun lies in the xz-plane. The spacecraft frame is 
   defined with +z in the orbit plane and +y along the orbit anti-normal.

   Since version 1.

   Form:
   [yaw, saAngle, yawRate, sARate] = SunNadir( xNoSun, orbitRate, beta, alpha, alphaLimit )
   [yaw, saAngle, yawRate, sARate] = SunNadir( xNoSun, orbitRate, beta )
   [yaw, saAngle, yawRate, sARate] = SunNadir( xNoSun, orbitRate )
                                     SunNadir( xNoSun, orbitRate, beta, alpha, alphaLimit )
                                     SunNadir( xNoSun, orbitRate, beta )
                                     SunNadir( xNoSun, orbitRate )
                                     SunNadir
