The laboratory data were reported by

While 23Na and 14N hyperfine splitting was resolved
in the laboratory, it is probably not important for observational purposes.
Nevertheless, a separate calculation with
Na and N hyperfine splitting is available for
J" ≤ 5 along with adjusted
partition function values.
The calculations should be quite reliable up to at least 50 GHz.
The dipole moment was taken from a quantum chemical calculation
in (1).
