| Keeps track of objects chosen by target selection and need to be tiled. |
| Objects are added whenever target selection is run on a new chunk. Objects are also added when southern target selection is run. In the case where an object (meaning run,rerun,camcol,field,id) is targetted more than once, there will be only one row in Target for that object, but there will multiple entries for that Target in the TargetInfo table. |
