*  Name:
*     palNutc

*  Purpose:
*     Calculate nutation longitude & obliquoty components

*  Language:
*     Starlink ANSI C

*  Type of Module:
*     Library routine

*  Invocation:
*     void palNutc( double date, double * dpsi, double *deps, double *eps0 );

*  Arguments:
*     date = double (Given)
*        TT as modified Julian date (JD-2400000.5)
*     dpsi = double * (Returned)
*        Nutation in longitude
*     deps = double * (Returned)
*        Nutation in obliquity
*     eps0 = double * (Returned)
*        Mean obliquity.

*  Description:
*     Calculates the longitude * obliquity components and mean obliquity
*     using the SOFA library.

*  Authors:
*     TIMJ: Tim Jenness (JAC, Hawaii)
*     {enter_new_authors_here}

*  Notes:
*     - Calls eraObl06 and eraNut06a and therefore uses the IAU 206
*       precession/nutation model.
*     - Note the change from SLA/F regarding the date. TT is used
*       rather than TDB.

*  History:
*     2012-03-05 (TIMJ):
*        Initial version
*        Adapted with permission from the Fortran SLALIB library.
