Content description based on the data set catalog file description for the PDS3 version, EAR-A-VARGBDET-3-KBOMAGS-V1.0
======================================================================================================================

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.
                                                           
    This data set contains absolute V-band magnitudes of 90 Kuiper            
    belt objects and Centaurs from Romanishin and Tegler (2005).   The        
    absolute magnitudes are derived from V magnitudes presented in            
    Tegler and Romanishin 1998, 2000, and 2003, Romanishin and Tegler         
    1999, and Tegler et al. 2003.  The phase correction was made using        
    H,G with an assumed value of G = 0.15.                                    
                                                                              
    For convenience, R-band absolute magnitudes derived from the V            
    absolute magnitudes and published V-R colors are also provided.           
    Both the V and R-band absolute magnitudes are reproduced from             
    Table 1 of Romanishin and Tegler (2005).  See this paper for              
    further details about the derivation.

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

    For the majority of objects, H(V) was determined from observations        
    taken only during one night, or perhaps a few nights during one           
    observation run.  For details of the analysis see the original            
    paper, Romanishin and Tegler (2005).
