Table 2:

Hyperfine constants and central frequency of the $J_K = 1_0 \leftarrow 0_0$ transition of NH3.
\begin{displaymath}{\small\begin{tabular}{lD{.}{.}{9}D{.}{.}{9}} \hline\hline \\... ...~498.15977(20) & 572~498.15994(19)\\ \hline \end{tabular}} \end{displaymath}

$^{\rm a}$ Hf-constants with their errors from Marshall & Muenter (1981) were fixed in the fit; $^{\rm b}$ standard errors from the fit are reported in units of the last quoted digit; $^{\rm c}$ in parenthesis is reported the statistical error from the fit; in addition, a systematic error of +2 kHz due to pressure shift has to be considered, see text.
