Notes. The coordinates of the O-rich stars are taken from the literature. An asterisk in the value of the luminosity (L⋆) or mass loss rate (Ṁ) indicates that the value has been scaled according to the updated value of the distance. (z) Assumed value for the condensation radius rc is 5 R⋆, for the dust temperature at the condensation radius Td(rc) is 1000 K, and for the gas-to-dust mass ratio Ψ is 300.
