Notes. Columns are (from left to right) designations of the targeted RSGs ratios of SiO(43 GHz peak flux)/SiO(86 GHz peak flux) ratio and SiO(86 GHz peak flux)/IR(8 μm flux) (see Alcolea et al. 1990). The 8 μm fluxes are taken from the MSX and GLIMPSE catalogs. Sources without measurements were not included in these surveys, or saturated in GLIMPSE.
