C NOTE:
C        IF:     n  =  number of ordinary/non-metastable levels
C            R(nxn) = Rate matrix (SEC-1) covering transistions between
C                     all possible pairs of ordinary levels.
C                     row   : final   level
C                     column: initial level
C                     (Inverse R-1(nxn) = 'CMAT(,)' )
C            V(n)   = Recombination rate vector (CM**3 SEC-1) covering
C                     all ordinary levels.
C                     ( = 'VEC()' - ordinary level part ).
C            S(n)   = Recombination contribution vector (CM**3) covering
C                     all ordinary levels ( = 'STV()' ).
C
C           Therefore:  R(nxn).S(n) = V(n)
C
C            =>         S(n)  = R-1(nxn).V(n)
