            O-C(X), O-C(Y) are published
          evaluation: The differences  O-C(X), O-C(Y) are published
                      in the article. For these values one have

                      The differences  O-C(X)e, O-C(Y)e were
                      calculated by N.Emelianov with the theory by
                      Harper & Taylor.  With these O-C one have
