FIG. 3.
Standard coordinate projection of the surface density of stars lying redward of and above the RGB tip. These stars are likely to be intermediate-age, moderate-metallicity thermally pulsing asymptotic giant branch stars. Of the substructure visible in the RGB map, only the northern spur is clearly detected on the AGB map; there is also marginal enhancement in the vicinity of the G1 clump. No corrections have been made for foreground or background contamination.
