This work also extended the transition frequency precision. The high $J$ cutoff is extended, but the listing is limited by the transition intensity cutoff, which now predicts all rotational transitions up the $J$ = 21, previously the intensity cutoff began to limit the prediction at $J$ = 10. The partition sums above 38 K are from HITRAN (TIPS) with a factor of six removed to reduce common factors in the degeneracies. The transition frequency data set from the previous catalog entry is retained in its entirety and includes: (1) B.J. Drouin, S. Yu, J.C. Pearson \& H.S.P.M\"{u}ller, J. Quant. Spectrosc. Radiat. Trans. 110, 2077-2081, 2009. (2) M. Womack, A. J. Apponi, L. M. Ziurys, 1996, Astrophys. J., 461, 897. The J" = 2 - 4 transition frequencies were reported by (3) V. Lattanzi, A. Walters, J. C. Pearson, and B. J. Drouin, 2008, J. Quant. Spectrosc. Radiat. Transfer, 109, 897. In addition, infrared ground state combination differences were used in the fit. These were published in (4) C. Chackerian, Jr., and G. Guelachvili, 1980, J. Mol. Spectrosc., 84, 447; (5) C. Chackerian, Jr., E. S. Bus, W. B. Olson, and G. Guelachvili, 1986, J. Mol. Spectrosc., 117, 255; (6) O. N. Ulenikov, G. A. Onopenko, N. E. Tyabaeva, J. Schroderus, and S. Alanko, 1999, J. Mol. Spectrosc., 193, 249. Since multiple experimental measurements exist for many of the THz transitions, no experimental data was merged with this catalog file.
