Representative mosaic (comprised of eight chips) image of the Sculptor Dwarf Spheroidal galaxy taken with the Magellan IMACS instrument in the V band. Nine fields of this size (﹩15\buildrel{\,\prime}\over{.} 46\times 15\buildrel{\,\prime}\over{.} 46﹩) cover the inner 45′ of Sculptor and, with at least two visits to each field, make up the imaging used in this study. HST ACS/WFC F814W footprint is outlined in orange. Stetson standard stars are circled in red (see Section 2.2); RRLs are circled in blue (see Section 4.3).
