Interstellar reddening (E(B − V)) map across the field of Sextans, centered at (R.A., decl.) = (153﹩\mathop{.}\limits^{\unicode{x000b0}}﹩26, −1﹩\mathop{.}\limits^{\unicode{x000b0}}﹩61). Iso-density contours are superimposed with red curves, while ellipses with semimajor axes of ﹩6^{\prime} ﹩, ﹩14^{\prime} ﹩, ﹩60^{\prime} ﹩, and ﹩84^{\prime} ﹩ are plotted with black curves, respectively. Blue dashed lines represent different Galactic latitudes. The single DECam field centered at (R.A., decl.) ∼ (158﹩\mathop{.}\limits^{\unicode{x000b0}}﹩5, −1﹩\mathop{.}\limits^{\unicode{x000b0}}﹩1) represents the reference field (see text for details).
