The authors are grateful to Dr. Tomonori Ikeura and Dr. Masayuki Takemura for their discussion, and our answers are summarized as follows ; (1) The smoothing process of the scaling factors in our calculation, not described in our paper, caused the difference between their results and ours, showing our final conclusions to be correct. (2) The averaged scaling factors in a high-frequency range were shown here to vary from n to about 2n/5 for n from 1 to 50, and not to be 1 as they insisted, in the case of method B at infinitely distant sites. But, the averaged scaling factors were concluded to be n in the actual syntheses as we had written in our paper.
