2  BURGUN 1972 is a final result which includes BURGUN 1971.
3  First GRAHAM 1972 value is second GRAHAM 1972 value combined with MANTSCH 1972.
4  Footnote 10 of HILL 1967 should read $+0.58$, not $-0.58$ (private communication) CHO 1970 is analysis of unambiguous events in new data and HILL 1967.
5  BALDO-CEOLIN 1965 gives $\mathit x$ and $\theta $ converted by us to Re($\mathit x$) and Im($\mathit x$).
6  FRANZINI 1965 gives $\mathit x$ and $\theta $ for Re($\mathit x$) and Im($\mathit x$). See SCHMIDT 1967.
