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)

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
