Abstract
The author wishes to thank Prof. Su for the careful reading of his paper and for reporting an issue with it. However, given Assumption 5(a) and the initialization (12) in von Ellenrieder (2019), it can be verified that if is not overly large, and is not overly small, then Theorem 1 of von Ellenrieder (2019) will hold and the proposed approach will be tenable.
