The composite of worst maneuvers is for the short stopover trips.

In every case, the outbound trip of the short stopover expedition can be substituted for the outbound trip shown for the long stopover expedition, 2: thus providing the flyby abort option in every case.

Observe that the outbound trip of the short stopover expedition is in each case identical with the outbound trip of the round trip flyby expedition. They could have been chosen otherwise, of course, but with only small advantage, mainly in respect to "window" width.

Perihelion distance less than 0.5 AU.

Entry at Earth exceeds 50000 feet per second.

Not calculated, but have been calculated for 1990 and 1997, and found comparable with values for 1978 and 1984, and presumably with values for 1971.

The numbers are mass fractions from the nominal trip tables.
