  Frame bias components of IAU 2000 precession-nutation models (part
  of MHB2000 with additions).
  
  This function is part of the International Astronomical Union's
  SOFA (Standards Of Fundamental Astronomy) software collection.
  
  Status:  canonical model.
  
  Returned:
  dpsibi,depsbi  double  longitude and obliquity corrections
  dra            double  the ICRS RA of the J2000.0 mean equinox
  
  Notes:
  
  1) The frame bias corrections in longitude and obliquity (radians)
  are required in order to correct for the offset between the GCRS
  pole and the mean J2000.0 pole.  They define, with respect to the
  GCRS frame, a J2000.0 mean pole that is consistent with the rest
  of the IAU 2000A precession-nutation model.
  
  2) In addition to the displacement of the pole, the complete
  description of the frame bias requires also an offset in right
  ascension.  This is not part of the IAU 2000A model, and is from
  Chapront et al. (2002).  It is returned in radians.
  
  3) This is a supplemented implementation of one aspect of the IAU
  2000A nutation model, formally adopted by the IAU General
  Assembly in 2000, namely MHB2000 (Mathews et al. 2002).
