C  PURPOSE: TO  CALCULATE  AND STACK UP IN  'STVM'  THE METASTABLE LEVEL
C           RECOMBINATION  COEFFICIENTS  FOR  A  GIVEN  TEMPERATURE  AND
C           DENSITY.

C  SUBROUTINE:
C
C  INPUT :  (I*4)  NDMET   = MAXIMUM NUMBER OF METASTABLE LEVELS ALLOWED
C
C  INPUT :  (I*4)  NMET    = NUMBER OF METASTABLE LEVELS

C                            LEVELS EXCEPT THOSE INVOLVING LEVEL 1.

C                            VALUES FOR GIVEN TEMPERATURE AND DENSITY.

C           (I*4)  IP      = PARENT INDEX
C
C  INPUT :  (R*8)  VRED(,) = VECTOR  OF RECOMBINATION RATE CONTRIBUTIONS
C                            FOR EACH METASTABLE LEVEL.
C                            (UNITS: SEC-1)
C                            VALUES FOR GIVEN TEMPERATURE AND DENSITY.
C                            DIMENSION: METASTABLE LEVEL INDEX
C
C  OUTPUT:  (R*8)  STVM()  = RECOMBINATION  CONTRIBUTION  FOR  EACH
C                            METASTABLE LEVEL. (UNITS: CM**3)
C                            VALUES FOR GIVEN TEMPERATURE AND DENSITY.
C                            (LEVEL 1 IS TAKEN AS ZERO)
C                            DIMENSION: METASTABLE LEVEL INDEX

C           (I*4)  IM2     = METASTABLE LEVEL ARRAY INDEX
C
C
C ROUTINES: NONE
C
C NOTE:
C           STVM(IM1)       SUM( (the transistion rate from IM2 to IM1)
C                                x (the recombination rate contribution
C                                   for metastable level IM2) )
C
C                           (IM1 & IM2 = METASTABLE LEVEL INDEX)
C
C                           ABOVE SUM IS OVER ALL METASTABLE LEVELS
C                           EXCEPT LEVEL ONE.
