a) AKARI S9W (9 μm), b) L18W (18 μm), c) N160 (160 μm) band maps of RCW38, shown together with the [CII] contour map in Fig. 1. The color levels are given in units of MJy sr^-1. The AKARI maps are derived from the all-sky survey data. d) Same as panel c), but enlarged and compared with the NANTEN ¹²CO J = 1–0 contours (velocity range: − 3–+ 12 km s^-1), where the contour levels are linearly drawn from 30 to 100 K km s^-1 in 10 steps.
