Map of the ﹩{A}_{{K}_{S}}﹩ extinction of the Red Clump within the UKIRT field. This map uses the 2017 PSF photometry data with a ﹩{2}^{{\prime} }﹩ edge length. Each pixel on the map is therefore of size ﹩{2}^{{\prime} }\times {2}^{{\prime} }﹩. The grayed region within ∣b∣ ≤ 0﹩\mathop{.}\limits^{\unicode{x000b0}}﹩6 and ∣l∣ ≤ 1﹩\mathop{.}\limits^{\unicode{x000b0}}﹩2 is where we only declare lower limits on the extinction. The gray shading sits behind the map and does not affect the color of the pixels themselves.
