The experimental lines are from
(1) K. L. K. Lee, M.-A. Martin-Drumel, V. Lattanzi, B. A. McGuire, P. Caselli, and M. C. McCarthy, 2019, Mol. Phys. 117, 1381.
The data should be sufficient for observational purposes. Transition frequencies involving Ka = 2 should be viewed with very great caution. All others should be viewed with caution once the calculated uncertainties exceed 0.2 MHz.
The ab initio dipole moment components are from (1).
