\caption{Graphical description of how \texttt{ObjID} is calculated from RA and Dec. It is not recommended to derive the RA and Dec from the \texttt{objID} as this will result in an innaccurate RA and Dec, the \texttt{ObjID} is assigned when the stack/skycal cmfs are ingested into the database, and are not yet calibrated against 2MASS and Gaia. ObjID is primarily used for indexing the database. }
