Notes.

^aThe complete table (Table A.1) is available at the CDS.

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