The 2 files "SRNH2AX.txt" and "SRNH2BX.txt" contain the output from the least squares fits of the respective data sets to a doublet asymmetric rotor program. The final output parameters are the same as in Table II of the manuscript. Each data point is characterized by upper and lower state quantum numbers J, Ka, Kc, and parity "E" or "F". For the lower state and Ka=0 in the upper states levels with J=N+1/2 are "E" and those with J=N-1/2 are "F". For levels with Ka>=1 in the A state "F" levels are the F1 and "E" levels are the F2 components. These are reversed for the B state. The observed line position, error from the fit, and estimated precision of each data point are given.
Levels designated parity = U have unresolved spin-rotation structure.
Levels designated Kc = -1 have unresolved asymmetry splittings.
The term energies for all levels are given at the end.
Both tables were produced using WordPad and saved as ASCII text. They should be readable with any text editor.
