  Equation of the equinoxes, compatible with IAU 2000 resolutions.
  
  This function is part of the International Astronomical Union's
  SOFA (Standards Of Fundamental Astronomy) software collection.
  
  Status:  support function.
  
  Given:
  date1,date2  double    TT as a 2-part Julian Date (Note 1)
  
  Returned (function value):
  double    equation of the equinoxes (Note 2)
  
  Notes:
  
  1) The TT date date1+date2 is a Julian Date, apportioned in any
  convenient way between the two arguments.  For example,
  JD(TT)=2450123.7 could be expressed in any of these ways,
  among others:
  
  date1          date2
  
  2450123.7           0.0       (JD method)
  2451545.0       -1421.3       (J2000 method)
  2400000.5       50123.2       (MJD method)
  2450123.5           0.2       (date & time method)
  
  The JD method is the most natural and convenient to use in
  cases where the loss of several decimal digits of resolution
  is acceptable.  The J2000 method is best matched to the way
  the argument is handled internally and will deliver the
  optimum resolution.  The MJD method and the date & time methods
  are both good compromises between resolution and convenience.
  
  2) The result, which is in radians, operates in the following sense:
  
  Greenwich apparent ST = GMST + equation of the equinoxes
  
  3) The result is compatible with the IAU 2000 resolutions.  For
  further details, see IERS Conventions 2003 and Capitaine et al.
  (2002).
