Description:
    Expansion coefficients  of the  polynomial expansion  representing the
    transition  D-values  for  the  {DELTA}v=1  band  and  the  12C16O
    isotope.  Results  are  obtained  using  the  Electric  Dipole  Moment
    Function EDMF2 (Langhoff & Bauschlicher  1995,  J.  Chem.  Phys.  102,
    5220). The fits are better than 1% when |m|≤mmax.

   1-  2  I2    ---     v''       Lower vibrational quantum number
   4-  6  I3    D       [mmax]  Rotationless transition matrix element
   8- 18  E11.4 ---     a0        Constant for n=DELTAv (1)
  20- 28  E9.2  ---     a1        First-order coefficient for n=DELTAv (1)
  30- 38  E9.2  ---     a2        Second-order coefficient for n=DELTAv (1)
  40- 48  E9.2  ---     a3        Thrid-order coefficient for n=DELTAv (1)
  50- 58  E9.2  ---     a4        Fourth-order coefficient for n=DELTAv (1)

Note (1): Each sequence and each vibrational band have been fitted with
     a fourth order polynomial form by using a numerical minimax procedure 
     from the Nag mathematical library as a function of
     m=[J'(J'+1)-J"(J"+1)]/2, v" and {DELTA}v=n
