\caption{\label{abundance}Circumstellar SiO fractional abundance, $f_{0}$, radius of the SiO line-emitting region from Eq.~(\ref{re}), $r_{\rm{e}}$, and gas expansion velocities derived from fitting the SiO line radiative transfer model to the observations, $v_{\rm{e}}(\rm{SiO})$. The reduced~$\chi^{2}$ for the best-fit model and the number of observational constraints, $N$, are also given.}
