    1313  \class SOPHYA::LocalMap
     14  \ingroup SkyMap
    1415  A local map is a 2 dimensional matrix, with ny rows and nx columns.
    15   The local map has an origin in (theta0, phi0), mapped to pixel(x0, y0)
    16  default value of (x0, y0) is middle of the map, center of pixel(nx/2, ny/2)
     16  The local map has a spatial origin with spherical coordinates (theta0, phi0), mapped to pixel(x0, y0). Default value of (x0, y0) is middle of the map, center of pixel(nx/2, ny/2).
     17
    1718 Each pixel(ip, it) is defined by its "phi-like" index ip (column
    1819 index in the matrix) and its "theta-like" index it (row index in
    … …  
    2021 system ; index it is associated with y-axis in the same map-coordinate system.
    2122 
    22     The map is supposed to lie on a plan tangent to the celestial sphere
    23     at a point, with spherical coordinates (theta0, phi0), whose pixel
    24     numbers  are (x0,y0) in the local map. The aperture of the map is defined
    25     by two values of angles, angleX and angleY, covered respectively by all
    26     the pixels in x direction and all the pixels in y direction.
     23    The map is supposed to lie in a plan tangent to the celestial sphere
     24    at its origin, with spherical coordinates (theta0, phi0), whose pixel
     25    numbers  are (x0,y0) in the local map as indicated above. The aperture of the map is defined by two values of angles, angleX and angleY, covered respectively by all the pixels in x direction and all the pixels in y direction.
    2726
    2827    Each pixel has angleX/nx and angleY/ny, as angle extensions. So, in

    37     The projection (method : ProjectionToSphere() )of the map onto a
     36    The projection (method : ProjectionToSphere() ) of the map onto a
    3837    sphere is made by the following procedure :
    3938
    4039    the sphere is supposed to have radius=1. The map is
    41     considered to be tangent to the sphere, on a point with (theta0, phi0)
     40    considered to be tangent to the sphere, at a point with (theta0, phi0)
    4241    spherical coodinates. A reference coordinate system (plane-coordinate
    43     system) , is chosen in the plane of the map  with reference axes :

    45     x-axis : vector tengent to a parallel in (theta0, phi0) on the sphere
     42    system) , is chosen with respect to the plane of the map  with reference axes :
     43
     44    x-axis : vector tangent to a parallel at (theta0, phi0) on the sphere
    4645    (components in "3-dim cartesian system : -sin(phi0) ; cos(phi0) ; 0)
    4746
    … …  
    4948             sin(theta0)*cos(phi0) ; sin(theta0*sin(phi0) ; cos(theta0)

    51     y-axis = z-axis^x-axis : tangent to the meridian at (theta0, phi0)
     50    y-axis : z-axis^x-axis : tangent to the meridian at (theta0, phi0)
     51
    5252
    5353    note that the map-coordinate system may be rotated with respect to
    … …  
    5858    his coordinates  in the plane-coordinate system (computed from x,y
    5959    above, with eventual rotation), with the sphere.
     60
     61   In order to make an instance of this class  available, the user must either use the standard constructor LocalMap() (as well as the "full" constructor LocalMap() ) or use the "partial" constructor LocalMap() followed by call to SetSize() and SetOrigin() (for fixing links between the map and the celestial sphere.
     62
     63Example :
     64
     65\verbatim
     66  LocalMap<r_4>    lcm(300, 600, 10.,20., 90.,0.); // full cstr.
     67\endverbatim
     68
     69defining a local map 300X600 pixels, representing a sphere portion of angular apertures 10 degres x 20 degres, with map center located on the equator, is equivalent to :
     70
     71\verbatim
     72  LocalMap<r_4>    lcm(300, 600); // partial cstr.
     73  lcm.SetSize(10., 20.);
     74  lcm.SetOrigin(90., 0.);
     75\endverbatim
     76
     77as well as :
     78
     79
     80\verbatim
     81  LocalMap<r_4>    lcm(300, 600, 10.,20., 90.,0., 0, 0); // full cstr.
     82\endverbatim
     83
     84(same map, but with origin of coordinates at pixel (0,0) instead of (150, 300) as it was implicit above)
     85
     86is equivalent to :
     87
     88\verbatim
     89  LocalMap<r_4>    lcm(300, 600);
     90  lcm.SetSize(10., 20.);
     91lcm.SetOrigin(90., 0., 0,0);
