Note: for PDS3 data sets migrated to PDS4, the following text is taken
verbatim from the data set description and confidence level note of the
PDS3 data set catalog file. In these cases, some details may not be correct
as a description of the PDS4 bundle.

  the file containing all the spectra in a single file, individual            
  files for each spectrum are available in the 'split' subdirectory.


Known issues or problems with the data
======================================

    This data is a compilation of results reported in the published           
  literature.  Error estimates are given for the individual data              
  values.  The individual references are to be consulted for any              
  additional information regarding the confidence level of the                
  observations.

    This dataset underwent formal external review on March 31, 1995.

    The PDS Three Micron dataset is intended to comprise a relatively         
  coherent set of asteroid infrared spectrophotometry data taken by a         
  single group of researchers working together.  It does not purport          
  to be a comprehensive survey of all asteroid infrared                       
  spectrophotometry.
