All Tables

Table 1: Stars observed in this work. The stellar type is derived from the literature as are the mass loss rates (e.g. Loup et al. 1993) and the period (e.g. AAVSO data).
Table 2: Derived parameters of the different components of the SiO maser emission profile for each star. Only the well-identified components are given (distinct peak or strong wing emission separated from the bulk emission). Note that the polarization is fractional. The $\delta p$ is the rms derived from the $p_{\rm C}$ plot.
Table 3: Average magnetic field strengths derived from $p_{\rm C}$ .
