PhotoFamilyPhotoThis view contains objects which are in PhotoObjAll, but neither PhotoPrimary nor PhotoSecondary. These objects are generated if they are neither primary nor secondary survey objects but a composite object that has been deblended or the part of an object that has been deblended wrongfully (like the spiral arms of a galaxy). These objects are kept to track how the deblender is working.
