m_F322W2 versus (m_Fn_5W - m_F322W2) colour-magnitude diagram of 47 Tuc stars from Milone et al. (2023) and MA24. Cyan dots indicate all sources observed for 47 Tuc, yellow dots indicate confirmed cluster members according to the criteria described in Section 3.3, and grey dots indicate SMC members. The blue and the red lines indicate 12 Gyr isochrones for the 1G and 2G of the cluster, respectively. Some specific masses are labelled along the isochrones. The masses 0.5,0.4,0.3,0.25,0.2,0.15,0.12,0.1,0.09,0.085,0.08 M_⊙ are shown. Below 0.08 M_⊙ the models are spaced by 0.001 M_⊙ down to 0.06 M_⊙ for the 1G and to 0.058 M_⊙ for the 2G. Finally, the upper dashed green line represents the saturation limit (m_F322W2 ≃ 18.5), while the lower diagonal green line indicates the limit where proper motions are available (mpn_5w = 26.1 as in MA24, properly converted in m_F322W2).
