estimated dust temperatures are listed in Table \[tab:mdust\], where $T_\mathrm{d}(\beta =1)$ and $T_\mathrm{d}(\beta =2)$ denote the dust temperatures evaluated with $\beta =1$ and 2, respectively. For the mass absorption coefficient, we adopt $\kappa_{125}=25.9$ cm$^2$ g$^{-1}$ (i.e. the value for silicate), but the dust mass is simply proportional to $\kappa_{125}^{-1}$ if another value of $\kappa_{125}$ is adopted. The distance is taken from H08 for the common sample, and is estimated by using the Galactocentric velocity taken from the NASA/IPAC Extragalactic Database (NED)[^7] by assuming a Hubble constant of 75 km s$^{-1}$ Mpc$^{-1}$. The dust masses estimated with $\beta =1$ and 2 are denoted as $M_\mathrm{d}(\beta =1)$ and $M_\mathrm{d}(\beta =2)$, respectively. Although the complex dependence of quantities in equation (\[eq:mdust\]) makes it hard to obtain an analytical estimate of the uncertainty in $M_\mathrm{d}$, we have confirmed that the uncertainty is around a factor of 2 by varying the measured fluxes within the errors. From Table \[tab:mdust\], we observe that $M_\mathrm{d}(\beta =1)$ is systematically smaller than $M_\mathrm{d}(\beta =2)$ by a factor of $\sim 2.5$, mainly because of higher dust temperature for $\beta =1$.
