Species tag 057514

Transition frequencies were taken from
(1) L. Kolesniková, E. R. Alonso, S. Mata, and J. L. Alonso, 2017, Astrophys. J. Suppl. Ser., 229, Art. No. 26.
Spectroscopic parameters were estimated from the main isotopolog published by
(2) Y. Motoki, Y. Tsunoda, H. Ozeki, and K. Kobayashi, 2013, Astrophys. J. Suppl. Ser., 209, Art. No. 23;
and scaled. Fewer parameters than in (1) were needed to reproduce the data slightly better.
The predictions may be sufficiently reliable for astronomical observations. Caution is advised for transitions with predicted uncertainties exceeding 200 kHz.
The dipole moment was assumed to agree with that of the main species. b-type transitions can not be predicted reliably at present and were omitted.
