  Time scale transformation:  International Atomic Time, TAI, to
  Terrestrial Time, TT.
  
  This function is part of the International Astronomical Union's
  SOFA (Standards of Fundamental Astronomy) software collection.
  
  Status:  canonical.
  
  Given:
  tai1,tai2  double    TAI as a 2-part Julian Date
  
  Returned:
  tt1,tt2    double    TT as a 2-part Julian Date
  
  Returned (function value):
  int       status:  0 = OK
  
  Note:
  
  tai1+tai2 is Julian Date, apportioned in any convenient way
  between the two arguments, for example where tai1 is the Julian
  Day Number and tai2 is the fraction of a day.  The returned
  tt1,tt2 follow suit.
