AKARI ZE template maps
----------------------

Since these component model maps were derived from the ($I_\mathrm{WIDE-S}-0.30 \times I_\mathrm{WIDE-L}$) difference map, the surface brightness of the model map is fainter than the real brightness of the dust bands in the WIDE-S map. To construct dust-band template maps for the four FIS bands, we considered the temperatures of the dust-band components. As derived in section 3.1, the $\pm \timeform{1.4D}/\timeform{2.1D}$ and $\pm \timeform{10D}$ dust bands have radii of 1.86 a.u. and 2.16 a.u., respectively. It can thus be expected that the $\pm \timeform{1.4D}/\timeform{2.1D}$ and $\pm \timeform{10D}$ components have typical temperatures of $\sim 200$ K and $\sim 185$ K, respectively. We assume a temperature for the circumsolar ring component of 278 K, because the circumsolar ring is expected to be composed of dust in the Earth’s orbit (1 a.u.). If we assume that the dust temperatures of the dust bands are $T_{\rm d}
