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 DENIS program (Deep European Near-Infrared southern sky               
    Survey) was a ground-based survey of the southern sky with the aim        
    of providing an extensive I,J,Ks photometric catalog of point and         
    extended sources.  It was carried out at the 1.0 meter ESO                
    telescope at La Silla, Chile from late 1995 through the end of            
    1999.  The limiting magnitudes of the three bands I, J, and Ks            
    centered at 0.8, 1.25, and 2.15 microns are respectively 18.5,            
    16.5, and 13.5 to a sensitivity of about 2 sigma.                         
                                                                              
    The DENIS point source catalog was searched for known asteroids           
    numbered from 1 to 8000 on the basis of their predicted positions.        
    The ephemerides were computed by numerical integration and                
    Chebyshev Polynomial approximations of a 10-body problem                  
    (Bec-Borsenberger 1992).  The orbits of the planets were included         
    for completeness and were taken from JPL DE403 (Standish 1995).           
    As initial conditions, the osculating elements of the Lowell              
    Observatory Asteroid Orbital Elements Database were used.                 
                                                                              
    This resulted in 2190 matches in the DENIS catalog with 1931              
    different asteroids found.  The results were published in Baudrand        
    (2001 and 2004), constituting the first and second releases of the        
    asteroid results.  Both the first and second releases are included        
    in this data set.                                                         
                                                                              
    The data for this data set were obtained at the Centre de Donnees         
    astronomiques de Strassbourg.  The data tables obtained there were        
    modified in the following ways only.  The tables were concatenated        
    into a single table, the columns were rearranged, phase angle was         
    truncated to three digits after the decimal point, and DENIS image        
    number was converted from a real number with no digits after the          
    decimal point to an integer.

    See Baudrand (2001 and 2004) for a discussion of the photometric          
    reduction pipeline, the asteroid matching procedure, and the              
    photometric results.  The derivation of the predicted V magnitude         
    is not provided by the authors.
