Proof. Let F = {Fw}w∈Ω be a ∗-continuous frame for H with pre-frame operator TF and frame operator S. Then the set of all the operator duals of {Fw}w∈Ω is precisely the following {gw}w∈Ω = { ΓFw + ϕew − ∫ Ω 〈 S−1Fw , Fi 〉 ϕewdµ(ω) } w∈Ω , where {ew}w∈Ω is the standard orthonormal basis for L2(Ω,A), ϕ ∈ B∗ ( H, L2(Ω,A) ) , and Γ is an invertible adjointable operator on H.
