-**
-**  Transform an FK5 (J2000.0) star position into the system of the
-**  Hipparcos catalogue, assuming zero Hipparcos proper motion.
-**
-**  Given:
-**     r5           double   FK5 RA (radians), equinox J2000.0, at date
-**     d5           double   FK5 Dec (radians), equinox J2000.0, at date
-**     date1,date2  double   TDB date (Notes 1,2)
-**
-**  Returned:
-**     rh           double   Hipparcos RA (radians)
-**     dh           double   Hipparcos Dec (radians)
-**
-**  Notes:
-**
-**  1) This function converts a star position from the FK5 system to
-**     the Hipparcos system, in such a way that the Hipparcos proper
-**     motion is zero.  Because such a star has, in general, a non-zero
-**     proper motion in the FK5 system, the function requires the date
-**     at which the position in the FK5 system was determined.
-**
-**  2) 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.
-**
-**  3) The FK5 to Hipparcos transformation is modeled as a pure
-**     rotation and spin;  zonal errors in the FK5 catalogue are not
-**     taken into account.
-**
-**  4) The position returned by this function is in the Hipparcos
-**     reference system but at date date1+date2.
-**
-**  5) See also eraFk52h, eraH2fk5, eraHfk5z.
