Data Set Overview
  =================
 
  This data set is intended to include published broadband colors of
  centaurs and Transneptunian Objects (TNOs) published through
  December 2006.
 
  Data
  ====
 
  Data were collected from the published literature and include
  Johnson-Kron-Cousins color indices and one-sigma uncertainty values
  for 200 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.

Confidence Level Overview
  =========================
    We assume the R-bandpass used by the various observers is in the
    Kron-Cousins system, but that this cannot be verified for all of
    the measurements included in this data set.
 
    Refer to the individual published papers for the confidence level
    of any individual measurement.
