Sculptor Dwarf Spheroidal VI extinction- and reddening-corrected CMD using photometry from Magellan-Baade IMACS imaging. Foreground sources are removed using proper motions from Gaia EDR3 with its depth plotted as a black dashed line (see Section A for details). IMACS instrumental magnitudes are calibrated to the Stetson–Landolt VI system as described in Section 2.2.
