Density contours of stars in the RC regime with subgrouping by (u − g)₀ color, in the (K_s, u − g)₀ plane. While the bluer RC stars show a single faint clump in all fields, the pattern of the redder RC stars varies with longitude and latitude. In the redder RC regime, the bright (faint) clump is prominently observed in the fields of positive (negative) longitude, and both clumps are shown in the fields of l = 0.0°. The peak magnitudes of these bright and faint clumps of redder stars are almost the same regardless of Galactic position. We note that the single clump of the bluer stars is fainter than the faint clump of the redder stars. The horizontal dotted lines represent K_s0 mag = 12.7, 13.3, and 13.6, respectively.
