\caption{\label{tbl-2}The \ion{Ar}{i} line broadening characteristics.
Measured: total Stark {\it FWHM} ($W_{\rm t}^{\rm exp}$ in pm within~$\pm$12\% accuracy), electron Stark width ($W_{\rm e}^{\rm exp}$
in~pm within $\pm$12\% accuracy), ion Stark width ($W_{\rm i}^{\rm
exp}$ in pm within~$\pm$12\% accuracy), static ion broadening
parameter ($A^{\rm exp}$, dimensionless within~$\pm$15\% accuracy)
and ion-dynamic coefficient ($D^{\rm exp}$, dimensionless within~$\pm$20\% accuracy) at measured electron temperature ($T^{\rm
exp}$ in~10$^{\rm 3}$~K) and electron density ($N^{\rm exp}$ in~10$^{\rm 22}$~m$^{\rm -3}$). Ref represents the values given in
this work~(Tw) and those used from other authors: KM,~\citet{Kus96}; B, \citet{Bue69}; G, \citet{Ger61}; J,
