We used the C_ugi = (u-g)-(g-i) index to identify three chemically distinct sub-populations along the red giant branch and compared their spatial distributions. The most light-element enriched sub-population (P3) is more centrally concentrated; however, it shows a more extended distribution in the external regions of the c","authors_text":"Alessandra Mastrobuono-Battisti, Alfredo Zenteno, Alice Zocchi, Annalisa Calamida, Armin Rest, Catherine A.
