Caption: Fig. 1.

512 × 512 pixel² (594 × 594 arcsec²) section of a bias‐subtracted and flat‐fielded z′‐bandpass image from the PT before (top) and after (bottom) the fringing correction. The two images are stretched identically; in the top image, the fringing is roughly 10% of the background level, peak to peak.
