Table 5:

Circumstellar SiO fractional abundance, f₀, radius of the SiO line-emitting region from Eq. (2), $r_{\rm {e}}$ , 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.
