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observers, unpublished radar observations, and from more recent references than 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  In some cases, bounds from unpublished radar 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.
