Notes.

^aThe complete table (Table A.2) is available at the CDS.

^bJ′, $K_a^{\mathrm{\prime }},$ and $K_c^{\prime }$ represent the quantum numbers associated with the upper rotational level. J″, $K_a^{″}$, and $K_c^{″}$ represent the quantum numbers associated with the lower rotational level.

^cObserved experimental frequency.

^dUncertainty in the observed frequency.

^eDifference between the observed frequency and that derived from the fit.
