The analytic order of III for modular elliptic curves
Journal de théorie des nombres de Bordeaux, Tome 5 (1993) no. 1, pp. 179-184.

In this note we extend the computations described in [4] by computing the analytic order of the Tate-Shafarevich group III for all the curves in each isogeny class ; in [4] we considered the strong Weil curve only. While no new methods are involved here, the results have some interesting features suggesting ways in which strong Weil curves may be distinguished from other curves in their isogeny class.
