The lines, the Hamiltonian, and the fitting are described in 
H. S. P. M\"uller, C. E. Miller, and E. A. Cohen, 1997, 
J. Chem. Phys. {\bf 107}, 8292. The dipole moment was also from that study.  
The parameters 
used in the combined fit of both isotopomers and all 
observed vibrational states are archived under tag no. 111001.
