Top: fractions of 1P binaries (dots), 2P binaries (starred symbols), and mixed binaries (triangles) derived in this study against the logarithm of the radial distance from the centre of 47 Tucanae. Bottom: fraction of 2P stars as a function of radial distance, in logarithm scale, from the literature (Milone et al. 2017; Dondoglio et al. 2021; Marino et al. 2024a; Mehta et al. 2025). The vertical dotted, dashed, and dashed- dotted lines mark the core, half-light, and tidal radius, respectively, from the 2010 edition of the Harris (1996) catalogue.
