 * Revision 1.3  2006/05/26 09:00:11  j_novak
 * New members for multiplication or division by cos(theta).
 *
 * Revision 1.2  2003/11/05 15:27:52  e_gourgoulhon
 * Treatment of case ETATUN now possible by a simple call
 *  to set_etat_qcq(), thanks to a modification of the latter.
 *
 * Revision 1.1  2003/11/04 22:59:13  e_gourgoulhon
 * First version.
