C  ******************** FORTRAN 77 FUNCTION: AXETRD *********************
C
C  PURPOSE:  TO CALCULATE THE REDUCED ENERGY FOR FOUR TYPES OF 
C            TRANSITION
C
C  CALLING PROGRAM: VARIOUS ADAS101 CODES

C  FUNCTION:
C
C  INPUT:    (R*8)    E      =   TRANSITION ENERGY (Eij)
C            (R*8)    T      =   COLLIDING ELECTRON ENERGY AFTER 
C                                EXCITATION (Ej)
C            (R*8)    C      =   ADJUSTABLE SCALING PARAMETER
C            (R*8)    TL     =   Ej/Eij OR kTe/Eij
C            (I)      KTYPE  =   TRANSITION TYPE
C                                1 ELECTRIC DIPOLE
C                                2 NON ELECTRIC DIPOLE
C                                3 SPIN CHANGE
