Note: Most of the rotation periods were taken from Horizons. Slightly different
values may be available from Petr Pravec, Michael Hicks, Peter Brown, other
observers, unpublished radar observations, and from more recent references than
those cited on Horizons. In some cases, bounds from unpublished radar
observations were used.
