Left: m _F322W2 vs. m _F150W2 − m _F322W2 CMD of stars in field A (left). The inset shows a Hess diagram of the low MS of 47 Tucanae, where the main gaps and discontinuities are marked with colored arrows. Specifically the crimson arrows indicate the changes in slope at m _F322W2 around 23.3 and 24.5 mag, while the teal arrows correspond to the sharp gap at m _F322W2 ∼ 24.2, and the observed minimum in the luminosity function at m _F322W2 ∼ 25.3 mag. Right: m _F322W2 vs. m _F150W2 − m _F322W2 (top) and m _F322W2 vs. m _F115W − m _F322W2 CMDs (bottom) for faint MS stars and brown dwarfs. The stars observed in both CMDs are represented with colored symbols; specifically, the aqua, orange, and red colors indicate the dwarfs that populate the main MS segments, whereas the likely brown dwarfs observed in both data sets are colored brown.
