The heliocentric distances of the band pairs, the inclination angles of the dust bands and the locations of the ascending nodes derived from the AKARI maps are listed in Table \[tab:geometry\]. The heliocentric distances of the band pairs are 1.86 and 2.16 a.u., the inclination angles of the dust bands are $\timeform{1.0D}\pm\timeform{0.1D}$ and $\timeform{1.3D}\pm\timeform{0.1D}$, the ascending nodes are located at $112\pm6\degree$ and $95\pm5\degree$ for the $\pm\timeform{1.4D}/\timeform{2.1D}$ and the $\pm\timeform{10D}$ bands, respectively.
