Left panel: de-reddened CMD of the stars lying in the elliptical annulus 1.5′ ≤ rϵ ≤ 5.0′, with the (RGB and HB) ridge lines of the GCs NGC 2419 (dashed blue line) and Pal4 (continuous red line), de-reddened and shifted to the distance of VV124, as derived here. The ridge lines has been derived by us from public SDSS data. The thin vertical lines enclose the typical color range of HB (−0.2 < (g − r)0 ≤ 0.4) and RGB (−0.4 < (g − r)0 ≤ 1.4) stars; the latter range is expected to enclose also the Red Clump of an intermediate-age population. Right panel: the LF of the stars in the HB color range in the considered annulus (thick continuous line) is compared to the LF in the same color range from an equivalent area of f1 (dotted line). The thin long-dashed line is the LF of the stars in the RGB color range.
