Notes.  $T_{\rm eff}$ is the effective temperature, $T_{\rm c}$ the dust condensation temperature, $\mathbf{\tau}_{\lambda}$ is the optical depth at 0.55 $\mu $m, n is the density power index, D the distance to the star, $V_{\rm gas}$ the terminal velocity derived from CO line measurements, L the luminosity, $\dot{M}$ the mass loss rate, $M_{\rm d}$ is the dust mass , M the total dust and gas mass loss, $\dot{M}_{\rm ref}$ the mass loss derived from previous studies.
