PhotoObjAllPhotoThis table contains all measured parameters for all photometric objects. Because this table is huge, a variety of Views have been created:
  • PhotoPrimary: all photo objects that are primary (the best version of the object)
    • Star: Primary objects that are classified as stars.
    • Galaxy: Primary objects that are classified as galaxies.
    • Sky: Primary objects which are sky samples.
    • Unknown: Primary objects which are none of the above
  • PhotoSecondary: all photo objects that are secondary (secondary detections).
  • PhotoFamily:: all photo objects which are neither primary nor secondary. These are the parents of deblended objects.
