This is the full-depth NUV image from GALEX eclipse 1516. It contains clear examples of several common categories of artifacts. Box A contains an “edge” artifact that is caused by the glint of a bright star just outside of the detector FOV. Box B contains a diffuse “halo” artifact caused by the light of a relatively bright star reflecting within the telescope optical chain. Box C contains two active hotspots, characterized by a bright spiral pattern (tracing out the inverse path of the boresight dither). This region also contains part of a diffuse artifact that is an extension of the edge artifact identified in A; such artifacts sometimes extend completely across the detector.
