Postage stamps for the face-on spiral UVCANDELS 25207 show in F435W a bright bulge and clear spiral arms. In F275W, the spiral arms are also clear, with bright knots along the lower arm and a particularly bright knot at the apparent end of an arm on the far left. This knot, and several lower-image clumps, appear in the SFR density map, though these knots are small and hard to distinguish in all four property maps. Spiral arms are faintly visible in SFR density, but stellar mass density and AV show no strong patterns. The t50 map, however, shows younger regions tracing the spiral arms and central bulge.
