  This data set contains 81 published spectra of asteroids                    
  obtained by Faith Vilas during the years 1982 - 1992.  These                
  appeared in the following papers:

  This data set first entered the PDS archives following its                  
  successful external peer review on 23 March 1998.                           
                                                                              
                                                                              
  Parameters

  Each spectrum is contained in a separate file, and lists                    
  wavelength, reflectance and error.  The index file for this                 
  collection contains observation dates, visual magnitude,                    
  integration time, phase angle, solar elongation, geo- and                   
  heliocentric distances, airmass, wavelength coverage limits,                
  normalization wavelength and solar analog stars for each spectrum           
  included.  An additional files lists identification(s), visual              
  magnitude, spectral type, position, and Hardorp class for each of           
  the solar analog stars referred to in the spectrum files.
