            <Description> Heliocentric Inertial (HCI) Frame :             
             * The solar rotation axis is the primary vector: the Z axis points in the solar north direction;  
             * The solar ascending node on the ecliptic of J2000 forms the X axis. 
             * The Y axis is Z cross X, completing the right-handed reference frame.            
              Solar longitude (Ls) :
  * The solar longitude Ls is the Planet-Sun angle, measured from the Northern Hemisphere spring equinox where Ls=0.
Ls=90 thus corresponds to northern summer solstice, just as Ls=180 marks the northern autumn equinox and Ls=270 the northern winter solstice.</Description>
