Target stars (filled red triangles and filled blue squares) in equatorial coordinates and proper motion, taken from Gaia EDR3 (top half of the panels), and in the 2MASS and Gaia CMDs (bottom two panels). The open red and blue circles indicate member candidates selected based on color and magnitude criteria (see text). Our data are shown together with nearby APOGEE stars within a circle of 15′ radius around Camargo 1103 and 1106 (gray circles). The black circles in the top panels are circles with radii of 3′ (Camargo 1103) and 2′ (Camargo 1106), in which Camargo (2018) selected member stars. The gray dots in the CMDs are full stars of 2MASS catalog (< 10′ radius from the center). The dotted, dashed, and solid lines in the CMDs are BaSTI isochrones of 13.5 Gyr and [Fe/H] = −1.80 dex for Camargo 1103 and 12.5 Gyr and [Fe/H] = −1.5 dex for Camargo 1106 (Pietrinferni et al. 2021) with E(B − V)=1.0, 1.5, and 2.0 mag, respectively, to account for the uncertain reddening.
