Left: proper motions for stars in field C brighter than m F322W2 = 24.0 mag. Stars in 47 Tucanae, within the red dotted circle, and SMC are clearly separated in this plot. Right: m F322W2 vs. m F110W − m F160W + m F115W − m F322W2 pseudo-CMD for probable cluster members (black circles), which are located within the red dotted circle in the left panel and for SMC stars (red crosses).
