Problem:This profile of a cosmic ray shows that it is pointlike. The plot looks like a delta function (remaining at constant sky brightness until suddenly rising steeply) rather than a more gaussian profile a star would exhibit. |
Fix:Take multiple images and median combine them. This will remove the cosmic rays from the final combined image. |
