In our paper a more detailed investigation of our spin-spin correlation bas revealed a slightly
diiferent picture.
One bas to replace trie sentence on p. 1574 bottom
"The peak is now splitting into two peaks or at least giving rise to a very broad mountain at

"The peak is no longer growing with U but reveals a broad maximum at (7r, 7r)."
