Upper panel: JWST CMD with stars in the 0"-70" annular region from the center, with a zoomed-in view of the MS-TO region. The selection boxes are the ones adopted to extract the sub-populations of different ages, each highlighted with a different color: red, blue, green, and yellow for the components aged 12.5 Gyr, 4.7 Gyr, 3.8 Gyr, and younger than 3.8 Gyr, respectively. Lower panel: cumulative radial distributions of the selected components (solid lines with the same color-code as in the upper panel). A sample of Galactic field stars (dashed black line) is also shown as reference.
