UVCANDELS 22456 is an inclined spiral galaxy. Strong clumps trace the spiral arms in F435W and are also clear in F275W. These clumps are not evident in SFR or stellar mass density maps, though the brightest F275W clump appears only faintly in SFR density. The t50 and AV maps show no clear patterns, but AV is higher in the brightest regions, which may explain the weak SFR inferred from SED fits there.
