Data Set Overview
  =================
 
  This data set is intended to include published broadband colors of
  centaurs and Transneptunian Objects (TNOs) published through December
  2004.
 
  Data
  ====
 
  Data were collected from the published literature and include
  Johnson-Kron-Cousins color indices and one-sigma uncertainty values for
  160 objects.  Many objects have data reported by several groups.  Details
  of the observations and data reduction are to be found in the individual
  papers.
 
  Archiving History
  =================
 
  The TNO colors data set, EAR-A-3-RDR-TNO-PHOT, was first introduced in
  2000 and was updated annually since then.  At the 2004 review, a data set
  compiling colors of Centaurs was also introduced, and it was decided to
  combine the two to make a new data set.  A column was added to the data
  table to indicate whether the object is a TNO or a Centaur.  Note that
  scattered disk objects are marked as TNOs, not as Centaurs.  This data
  set supersedes all the versions of the TNO colors data set,
  EAR-A-3-RDR-TNO-PHOT.  This is the second version of the combined
  TNO/Centaur data set.
