 * $Log: valeur_coef_i.C,v $
 * Revision 1.14  2012/01/17 15:08:02  j_penner
 * using MAX_BASE_2 for the phi coordinate
 *
 * Revision 1.13  2009/10/23 12:56:29  j_novak
 * New base T_LEG_MI
 *
 * Revision 1.12  2009/10/13 13:49:58  j_novak
 * New base T_LEG_MP.
 *
 * Revision 1.11  2009/10/08 16:23:14  j_novak
 * Addition of new bases T_COS and T_SIN.
 *
 * Revision 1.10  2008/10/07 15:01:58  j_novak
 * The case nt=1 is now treated separately.
 *
 * Revision 1.9  2007/12/11 15:28:25  jl_cornou
 * Jacobi(0,2) polynomials partially implemented
 *
 * Revision 1.8  2004/11/23 15:17:19  m_forot
 * Added the bases for the cases without any equatorial symmetry
 *  (T_COSSIN_C, T_COSSIN_S, T_LEG, R_CHEBPI_P, R_CHEBPI_I).
 *
 * Revision 1.7  2004/08/24 09:14:52  p_grandclement
 * Addition of some new operators, like Poisson in 2d... It now requieres the
 * GSL library to work.
 *
 * Also, the way a variable change is stored by a Param_elliptic is changed and
 * no longer uses Change_var but rather 2 Scalars. The codes using that feature
 * will requiere some modification. (It should concern only the ones about monopoles)
 *

 * Revision 1.2  2002/10/16 14:37:15  j_novak
 * Reorganization of #include instructions of standard C++, in order to
 * use experimental version 3 of gcc.
