UVCANDELS 08062 has a bright off-center feature most clearly seen in F275W and F435W, with F435W also revealing internal structure. The segmentation map shows peak SFR density at the center, with elevated SFR density at the bright feature just right of center. The SFR and stellar mass density maps both show an arc of enhanced density above this feature. The t50 map indicates the bright clump is younger than the rest of the galaxy, with additional young regions toward the bottom and a smaller knot visible only in F435W in the upper right. AV is fairly uniform, except for higher values on the bulge.
