Spatial distributions of the AKARI/MIR sources in density maps in the Galactic coordinates of the Aitoff projection. These sources are classified on the basis of the  [9]  −  [18]  vs.  [J]  −  [K]  color–color diagram alone (candidate samples). We show groups A, C, D, E, and F because they have a sufficiently large number of members. The color scales are linear from 0% to 50% of the peak value and given in units of deg^-2. The coordinate grids and the locations of the Galactic bulge, the LMC, the SMC, and the nearby star-forming regions are shown in the lower right panel.
