Radiative decays of light- and heavy-flavor tensor mesons

New data are used to reexamine $T\to V_{\gamma }$ and $T\to \gamma \gamma$ decays. Their strength is determined from sum rules involving experimentally determined quantities. One of two models considered is in excellent agreement with the measured $f^0$, $A_2^0\to \gamma \gamma$ transitions. The model is extended to calculate radiative decays of strange and charmed tensor mesons.
