Given an isogeny class of abelian varieties defined over a finite field $\F_q$, its Weil polynomial is such that all of its roots $\alpha_1,\alpha_2, \ldots, \alpha_{2g}$ have absolute value $\sqrt{q}$. Therefore all of the information on the roots is contained in the quantities
$${\rm Arg}(\alpha_i)$$
which we call the **Frobenius angles** of the Weil polynomial.
