\sim 185$ K, 200 K, and 278 K, their brightnesses relative to those of the WIDE-S band data are 1.376, 1.390 and 1.439 for the N60 band, 0.212, 0.208 and 0.193 for the WIDE-L band, and 0.133, 0.130 and 0.119 for the N160 band, respectively. To construct the corresponding dust-band maps in the four FIS bands for the circumsolar-ring component ($T=278$ K), we multiplied the brightness of the component model by the following factors:

-   N60: $1.439/(1.0-0.30 \times 0.193) = 1.53$;

-   WIDE-S: $1.0/(1.0-0.30 \times 0.193) = 1.06$;

-   WIDE-L: $0.193/(1.0-0.30 \times 0.193) = 0.20$;

-   N160: $0.119/(1.0-0.30 \times 0.193) = 0.13$.

The $\pm \timeform{1.4D}/\timeform{2.1D}$ and $\pm \timeform{10D}$ band-pair maps were derived similarly, and we constructed the AKARI dust-band templates using these component maps as follows.

The publicly released AKARI maps have been processed with data in both the leading and trailing directions obtained during different semi-annual seasons. To construct the ZE template of the dust bands for the AKARI maps, we need to take into account the numbers of observations of the leading and the trailing scans for each pixel. Figure \[fig:season\] shows which of the leading and trailing scans cover the relevant sky regions. During the first 6
