  DESCRIPTION        = "This table presents the Seven Color Asteroid          
    Survey spectrum for (951) Gaspra.  The Seven Color Asteroid Survey        
    (SCAS) filter system was specifically designed to capture the essential   
    mineralogic information present in infrared asteroid spectra. It is       
    composed of seven broad-band filters lettered A through G in order        
    of increasing wavelength, covering the spectral region 0.9 to 2.3         
    microns. (The asteroid (243) Ida was not included in this survey.)        
                                                                              
    Note:  The B-D band difference is a strong indicator of the main          
    source of variation in the SCAS data set.  B-D can be used to             
    distinguish between typical S-class asteroid spectra and typical          
    K-class spectra.  B-D essentially measures the depth of the               
    1-micron absorption feature.
