Graphical description of how objID is calculated from RA and decl. It is not recommended to derive the RA and decl. from objID as this will result in an inaccurate RA and decl. 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.
