Notes.  $T_{\rm eff}$ is the adopted effective temperature, $V_{\rm gas}$ the terminal velocity derived from CO line measurements, D the distance to the star, $\vec{\tau} _{\lambda}$ is the overall optical depth at 0.55 $\mu $m, $T_{\rm a}$ the inner temperature of the attached shell, $T_{\rm d}$ the inner dust temperature of the detached shell(s), $r_{\rm d}$ the inner radius of the detached shell(s), $Y_{\rm d}$ the detached shell(s) thickness in inner shell radius units, L the luminosity, $\dot{M}_a$ the actual mass-loss rate, $\dot{M}$ the mass-loss rate of the detached shell(s), and M the total dust and gas mass-loss.
