      Description

      When sources are near the edge of an exposure the masked EDGE region is ignored and the centroid is placed in the peak catalog at the nearest pixel to the edge mask. This results in a poor position for a potentially bright source, which is catastrophic to deblending with meas_extensions_scarlet.

      Example:

      Ideally it would be nice to get a better (noisy) centroid that located closer to the edge, allowing a better approximation for the source.
