% Compute the eclipse duration in earth orbit.
   Uses the orbit radius at perigee for the computation.

   The orbital elements are
   [Semi-major axis, Inclination, Right ascension of the ascending node,
   Argument of perigee, Eccentricity, Mean Anomaly]

   Type EarthEclipseDuration for a demo in a 7000 km 85 deg orbit.

   Uses SunBeta and EclipseDuration.

   d = EarthEclipseDuration( el, jD )

   el          (1,6) [a i W w e M]
   jD          (1,:) Julian date (days)

   d           (1,:) Eclipse duration (sec)
   dMax        (1,1) Maximum eclipse duration (sec)
