	The data set used is referenced by A. Bauder, F. J. Lovas, and D. R.
Johnson, 1976, J. Phys. Chem. Ref. Data {\bf 5}, 53.  The lines were fit
to a Hamiltonian that included terms up to the sixth power in angular momentum
as well as $P_a$, $P_a P^2$, $P_a P^4$, $P_a^3$, $P_a^3 P^2$, and $P_a^5$ terms.
The fit produced observed--calculated frequencies that were 3.5 times the
experimental uncertainties in an RMS sense. The calculated line strengths 
agree with those of Bauder {\it et al.}
