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 photometric lightcurves of near-earth                
  asteroids obtained by Petr Pravec and his collaborators at Ondrejov         
  Observatory.  Lightcurves for 42 asteroids are included.  These             
  asteroids were included based on a slightly wider criterion                 
  for a NEA:  q < 1.33 AU (rather than the standard definition of             
  q < 1.3 AU).  As a result, some asteroids may be included which             
  other researchers would classify as Mars-crossers.                          
                                                                              
  Parameters                                                                  
  ==========                                                                  
                                                                              
  The lightcurve files contain columns for light-corrected UTC                
  Modified Julian Date, and magnitude.  The type of magnitude is              
  specified in the parameter table.  Lightcurve files are divided into        
  subdirectories by asteroid number, with a separate subdirectory for         
  asteroids unnumbered at the time of the most recent update.  The            
  data file names start with the asteroid number (or provisional              
  designation for unnumbered asteroids) followed by the date of               
  observation.                                                                
                                                                              
  The parameter table has one line per lightcurve and gives the               
  subdirectory and filename, the asteroid number and/or provisional           
  designation, the starting and ending time of the lightcurve, the            
  color band and magnitude type, the phase to which the magnitudes            
  have been corrected, and the minimum and maximum errors of the              
  points of the lightcurve.
