  • If we call the black pixels (everything except for the galaxy blobs) ‘background’, what is the background-to-galaxy proportion on average. What is the distribution of this proportion over all images ?
  • Does the background consist only of purely black pixels? Is there any variation in the ‘blackness’ of the background ?
  • What is the distribution of the number of galaxies per image ?
  • What is the distribution of the size of the galaxies ?
