Panel a: surface number density profiles of RGB stars (bRGB – blue diamonds, rRGB – dark red squares), AGB stars (red circles), and pRGB stars (green asterisks) measured in elliptical annuli. Linear fits are shown for different segments of the profiles, and corresponding SL values are indicated in the legend (subscript numbers indicate the segments going from left to right). Vertical dashed lines indicate a limit for a crowded central part of the galaxy (, completeness at I = 22.5 is ∼80%), an edge of the distribution of bright AGB stars (a ∼ 4′), and a position of a prominent break in the rRGB profile (a ∼ 6′). Panel b: normalized cumulative distributions of AGB, pRGB, bRGB, and rRGB stars (colours are the same as in panel a).
