The data set used in this fit includes all the micorowave measurements
reviewed in J. C. Pearson, T. Anderson, E. Herbst, F. C. De Lucia and 
P. Helminger, 1991, Astrophys J. {\bf 379}, L41, additional measurements 
were used from J. C. Pearson, 1995, Ph.D. Thesis Duke University, S. 
Belov, 1996, Private Communication, F. Matsushima, H. Odashima, 
T. Iwasaki, S. Tsunekawa, K. Takagi, 1995, J. Mol.\ Struct.\ {\bf 352-353}, 
371, and P. Chen, J. C. Pearson, S. Matsuura, G. A. Blake and H. M. Pickett, 
1999, Astrophys.\ J., In Press.  FTIR rotational data was taken from 
J. Kauppinen, T. Karkkainen and E. Kyro, 1978, J. Mol.\ Spectrosc.\ {\bf 71}, 
15, J. W. C. Johns, 1985, J. Opt.\ Soc.\ Am.\ {\bf B2}, 1340, R. Paso and V. M.
 Hornman, 1995, J. Opt.\ Soc.\ Am.\ {\bf B12}, 1813 and R. A. Toth, 1999, 
Private Communication, FTIR band transitions were taken from R. A. Toth, 
1999, Private Communication and Energy Levels taken from R. A. Toth, 1998, 
J. Mol.\ Spectrosc.\ {\bf 190}, 379 and O. L. Polyansky, N. Zobov, S. Viti, 
J. Tennyson, P. Bernath and L. Wallace, 1997, J. Mol.\ Spectrosc.\ {\bf 186}, 
422. All the data was forced into the fit and a reduced RMS of 1.9 was 
obtained for a combined fit of the ground and $\nu_2$ data.  This 
represents the ground state version only.  It should be noted that there 
is minimal data at the highest J values.  The quoted errors are expected 
to be about 1/2$\sigma$. The fitting method is described in P. Chen 
{\it et al.}.  

The intensities were calculated using the method in C. Camy-Peyret 
{\it et al.}, 1985, J. Mol.\ Spectrosc.\ {\bf 113}, 208.  A value of 
1.84718 Debye was used along with corrections for the planarity 
conditions.  This agrees will with observed IR intensities up to 
$\Delta K_a=3$ transitions.  Higher order planarity terms are needed 
for agreement with $\Delta K_a=5,7,9...$ transitions.   The partition 
function includes the $\nu_2$ state.  Classical corrections for 
higher temperatures are given in P. Chen {\it et al.}.
