As written it suggests we foolishly replace some of the pixel estimates with "old" values, when of course we do not. The newer version that appears in our 1995 T-IP paper is correct, and supersedes the T-SP version. The proof of Theorem 2 incorrectly states that the eigenvalues of the Gauss-Siedel matrix are real. They can be complex, so the proof only applies to cases where the maximum magnitude eigenvalue is real. (.pdf)
