The data were taken from G. Wlodarczak {\it et al.}, 1986, J. Mol. Spect. {\bf 116}, 
251, and references cited therein.  Additional measurements up to $K=12$ were
made at JPL for $J=24-23$.  The dipole moment is from J. A. Golby and
R. J. Butcher, 1984, J. Mol. Spect. {\bf 107}, 292, but see also 
G. Wlodarczak {\it et al.}, 1985, J. Mol. Spect. {\bf 112}, 401. The vibrational portion of the partition function was added in version two and version three utilizes the spin group symmetry to produce accurate relative intensities.
