Notes. Column 1 gives the name of the Cepheid. Column 2 gives the effective temperature. A “*” after the temperature indicates that it changed w.r.t. the standard model. Columns 3–4 give the luminosity and error bar. Columns 5–6 give the dust optical depth at 0.55 μm and error bar. Columns 7–8 give the temperature at the inner radius and error bar. All error bars have been scaled to a reduced χ2 of unity. Column 9 gives the mass-loss rate, assuming a dust-to-gas ratio of 1/200, and an expansion velocity of 200 km s−1. The values should be used with extreme caution as they are uncertain by a factor of ten due to the uncertainties in the adopted expansion velocity, dust-to-gas ratio, dust opacity and the modelling itself.
