C  ******************** FORTRAN 77 FUNCTION: AXOURDV ******************
C
C  PURPOSE:  TO CALCULATE THE COLLISION STRENGTH OR UPSILON FROM THE 
C            REDUCED COLLISION STRENGTH OR REDUCED UPSILON
C            FOR FOUR TYPES OF TRANSITION

C
C  FUNCTION:
C
C  INPUT:    (R*8)    EIJ    =   TRANSITION ENERGY (Eij)
C            (R*8)    EJ     =   COLLIDING ELECTRON ENERGY AFTER 
C                                EXCITATION (Ej)
C            (R*8)    C      =   ADJUSTABLE SCALING PARAMETER
C            (R*8)    ETR    =   Ej/Eij
C            (I)      IXTYPE =   TRANSITION TYPE
C                                1 ELECTRIC DIPOLE
C                                2 NON ELECTRIC DIPOLE
C                                3 SPIN CHANGE
C                                4 OTHER
C            (R*8)    DGEY   =   REDUCED COLLISION STRENGTH
