Caption: Figure 2.

Color–magnitude diagrams of the galaxies NGC 1448 and NGC 1316. Likely TP-AGB stars are visible above the Red Giant Branch, although an abrupt jump in the luminosity function of each CMD, shown later in Section 3.5, still clearly marks the location of the TRGB. Median magnitude and color error bars are plotted alongside the CMDs.
