Photometric diagrams demonstrating the photometry used to disentangle the multiple populations in different radial regions of 47 Tucanae. Panel a shows the HST UV photometry used to identify populations in the RGB. In panel b, we show the CMD created using HST optical filters for Field A. Panel c demonstrates the CMD created for the lower MS and substellar objects with JWST filters for Field C. Panel d displays HST IR photometry for disentangling populations among the lower MS. In panel e, we show Ca-CN photometry by Lee (2022), which is effective in identifying populations among RGB and HB stars. Panel f displays the diagram with ground-based UBVI photometry from Stetson et al. (2019). Finally, in panel g), we show the CMD created with Gaia XP spectro-photometry (Mehta et al. 2025)
