The work of H. Gupta, B. J. Drouin, \& J. C. Pearson, 2012, ApJ, 
{\bf 751}, L38 and the optical spectra in W. D. Sheasley, 1972, Ph.D. Dissertation, 
The Ohio State University; Ann Arbor, MI. is expanded to include vibrational data from Dom\'enech, Drouin, Cernicharo \emph{et al.} ApJL 833 L32 (2016).
The transition dipole moments for infrared ($\mu'$ and optical ($\mu_{el}$) are calculated by A. Pradhan {\it et al.} 1991, 
J. Chem. Phys, {\bf 95}, 9010.  The magnetic dipole, which predicts fine structure transitions in the mid and far-ir was taken to be 1 Bohr magneton. The state identifiers v = 80 and 
v = 81 refer to the ground and first excited vibrational levels, respectively.  The  $^2\Sigma$ ground vibrational state has a state identifier of 40, and the state identifier 0 is
the $^2\Pi$ vibrational ground state without hyperfine splitting.

state identifier (v) & state & HFS\\

0 & $^2\Pi$ v = 0 & no \\
40 & $^2\Sigma$ v = 0 & no \\
80 & $^2\Pi$ v = 0 & yes \\
81 & $^2\Pi$ v = 1 & yes \\
