* $Log: map_af_radius.C,v $
* Revision 1.9 2014/10/13 08:53:03 j_novak
* Lorene classes and functions now belong to the namespace Lorene.
*
* Revision 1.8 2014/10/06 15:13:12 j_novak
* Modified #include directives to use c++ syntax.
*
* Revision 1.7 2013/06/05 15:10:42 j_novak
* Suppression of FINJAC sampling in r. This Jacobi(0,2) base is now
* available by setting colloc_r to BASE_JAC02 in the Mg3d constructor.
*
* Revision 1.6 2008/09/01 08:12:03 j_novak
* Improved test on the [rmin, rmax] interval.
*
* Revision 1.5 2007/12/11 15:28:14 jl_cornou
* Jacobi(0,2) polynomials partially implemented
*
* Revision 1.4 2006/09/13 13:59:21 j_novak
* Higher tolerance thereshold for Map_af::val_lx
*
* Revision 1.3 2006/07/10 07:44:51 j_novak
* Correction of the comparison between rmin and rr (now has to be greater than
* some threshold).
*
* Revision 1.2 2006/07/05 12:36:51 n_vasset
* Added a test on rmin to see whether the point lies in the computational domains.
