Notes. Column description (see also Sect. 2.2) for each isotopologue. Col. 1: J. Cols. 2 and 3: R_ms and P_ms wavelengths(nm). Cols. 4 and 5: R_ms and P_ms wavenumbers (cm⁻¹). Col. 6: δ_P wavenumber corrections applied to TV_P in units of the least significant digit (− δ_P is applied to TV_R). No value means no measurement for one of the branches, either R or P. An asterisk indicates, when both R- and P-branches are present at high J ′ , either the potential presence of a perturbing state or that one of the lines shows a larger uncertainty than the other. Cols. 7 and 8: Q_ms Q-branch wavelengthsand wavenumbers. ^(a) Data from Cacciani & Ubachs (2004). ^(e) Data calculated from the e-parity levels.
