N2 - We develop tools to determine the gluonic content of a resonance of known mass, width, and [Formula presented] from its branching fraction in radiative quarkonium decays and production cross section in [Formula presented] collisions. We test the procedures by applying them to known [Formula presented] mesons, then analyze four leading glueball candidates. We identify inconsistencies in data for [Formula presented] and [Formula presented] whose resolution can quantify their glueball status. When [Formula presented] and [Formula presented] are known, the [Formula presented] mixing angles can be determined. The enigmatic situation in the 1400–1500 MeV region of the isosinglet [Formula presented] sector is discussed.
