The final member selection for several dwarfs after frame matching and the iterative membership selection. The member stars are shown in blue and the nonmembers are shown in red. Left: the relative PMs from GAIAHUB analysis. Right: the CMD from the Gaia DR3 catalog. Leo I (upper panels), which represents the most certain result, Leo A (middle panels), which represents a typical result, and Leo T (lower panels), which represents our least certain result.
