1 From the TRIAD list published in "Morrison D., and Zellner B. (1979).     
 - Polarimetry and radiometry of the asteroids. Asteroids, 1090-1097".       
 2 A different albedo is reported in the list published in "Hamilton Brown,  
 - R., and Morrison, D. (1984). Diameters and albedos of thirty-six          
 - asteroids. Icarus 59, 20-24": the value can be from a pre-publication list
 - from them, or from the unpublished list of J. C. Gradie and E. F. Tedesco.

 - Matson, D. L., Kowal, C., Wynn-Williams, C. G., and Becklin, E. E. (1981).
 - The albedo and diameter of 1862 Apollo. Icarus 48, 335-338".              
 4 Reported in "Binzel, R. P., and Tholen, D. J. (1983). The rotation,       
 - color, phase coefficient, and diameter of 1915 Quetzalcoatl. Icarus 55,   
 - 495-497" as a personal communication of G. J. Veeder.

 - Rieke, G. H., and Lebofsky, M. J. (1984). 2060 Chiron - Visual and thermal
 - infrared observations. Icarus 60, 532-537", where they report a value of  
 - 0.10.

 - G. J., and Matson, D. L. (1983). 2100 Ra-Shalom: A Rocky Asteroid?        
 - Bulletin of the American Astronomical Society 15, 824", where it's        
 - reported as 0.055 (from a Thermal Inertia Model).

11 Reported as 1975 U2 in TRIAD and on the original list (probably a         
 - temporary designation given by the observer). Later identified with       
 - 1975 RC = 1992 WC1, but the identification is not certain.
