Caption: 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.
