The elementary right-averaging actions are continuous for pointwise weak-star convergence. Multiplication normality is used only in the output variable; the maps being averaged need not themselves be normal.

    Source documentation

    Right averaging acts on the ambient space of all weak-dual-valued functions, so its continuity also applies to closures of operator families.
