INDICES FOR TABLE  PhotoObjAll

Contains a record describing the attributes of each photometric object

The table has views:
  • PhotoObj: all primary and secondary objects; essentially this is the view you should use unless you want a specific type of object.
  • 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 no0ne of the above
  • PhotoSecondary: all photo objects that are secondary (secondary detections)
  • PhotoFamily: all photo objects which are neither primary nor secondary (blended)

The table has indices that cover the popular columns.
