Define respectively the coordinate projection system and the projection constants. The SYSTEM code can be 1 for UNKNOWN, 2 for EQUATORIAL (1950.0), 3 for GALACTIC. The projection code is 0 for NONE, 1 for GNOMONIC, 2 for ORTHOGRAPHIC, 3 for AZIMUTHAL, 4 for STEREOGRAPHIC, 5 for LAMBERT cylindrical, 6 for AITOFF equal area and 7 for RADIO (also known as global SINUSOIDAL) projection.

Arguments :
        ICODE   INTEGER         Input
        X       REAL            Input        Projection center
        Y       REAL            Input        Projection center
        A       REAL            Input        Projection Angle
