Square points artefact

  • Ouston by Ouston

    Are the four points forming a square in the top right have to be signaled ?
    Is it weird ?

    Hi Ouston and welcome to the Zoo

    These dots in a square are a fairly common artifact in these infrared images from the UKIDS Survey. No idea what causes them , sorry.

    happy hunting! 😄
