C  FUNCTION:
C
C  INPUT:    (R*8)    EIJ    =   TRANSITION ENERGY (RYD)
C            (R*8)    EJ     =   COLLIDING ELECTRON ENERGY AFTER 
C                                EXCITATION (RYD)
C            (R*8)    B      =   BURGESS SCALING PARAMETER - B
C            (R*8)    C      =   BURGESS SCALING PARAMETER - C
C            (R*8)    TL    =   Ej/Eij
C            (I)      KTYPE  =   TRANSITION TYPE
C                                1 ELECTRIC DIPOLE
C                                2 NON ELECTRIC DIPOLE
C                                3 SPIN CHANGE
C                                4 OTHER
C            (R*8)    OURED   =   REDUCED COLLISION STRENGTH
C
C  OUTPUT:   (R*8)    OURED9INV =   UPSILON
C
C            (I*4)    IASYMC =   ASYMPTOTIC CLASSIFICATION TYPE
C            (I*4)    ITHRSC =   THRESHOLD CLASSIFICATION TYPE
C            (R*8)    E0     =   SWITCHING ENERGY
