Bill's comments on the SAS 39 views StackObjectView is a join of three tables: ObjectThin StackObjectThin StackObjectAttributes Includes all columns from ObjectThin except for batchID. A few (bookkeeping) columns are dropped from StackObjectThin From StackObjectAttributes columns that are duplicates from the thin men are dropped. Mostly looks fine except for the projectionID skycellId issue that I mentioned in my wiki page That is the projectionID and skyCellID do not match the xStackMetaIDs I suggest change the view to incude the values from StackObjectThin instead and it would be useful to add StackObjectThin.primaryDetection and StackObjectThin.bestDetection At a higher level, given the ambiguity do ObjectThin projectionID & skycellID make sense? Perhaps they should be called primaryProjectionID, primarySkyCellID ? If that change were made to the schema then we could include both in StackObjectView, but I don't see what value that would add.
