Caption: Figure 14.

Shown are postage stamps and property maps of 10335 in pixel coordinates. Top: HST F275W, F435W, F814W, and F160W postage stamps. Bottom: 2D maps of log ΣSFR, ﹩{{\rm{\Sigma }}}_{{M}_{\ast }}﹩, t50, and AV. The warped or twisted feature is clear in the segmentation maps and especially in ΣSFR and ﹩{{\rm{\Sigma }}}_{{M}_{\ast }}﹩, but not in t50 or AV. A bright knot at the top of the twisted arm in F275W and F435W stands out in the ΣSFR, ﹩{{\rm{\Sigma }}}_{{M}_{\ast }}﹩, and t50 maps, indicating an older, more massive region currently undergoing elevated star formation. The object in the upper-left corner is very faint in all properties, suggesting it is a background source unrelated to 10335.
