Values of the phase integral for asteroids of differing geometrical albedo.

Complex	Geometrical albedo	Phase integral q
		Observations	HG function	HG₁G₂ function
Low albedo	0.061 ± 0.017	0.35 ± 0.02	0.34 ± 0.03	0.36 ± 0.02
Moderate albedo	0.20 ± 0.05	0.42 ± 0.02	0.45 ± 0.02	0.42 ± 0.02
High albedo	0.45 ± 0.07	0.54 ± 0.02	0.63 ± 0.04	0.56 ± 0.03
Average	0.24 ± 0.20	0.44 ± 0.10	0.47 ± 0.15	0.45 ± 0.10

Notes. The phase integral q for the observations was computed with numerical integration. The error bars are the 1 sigma dispersion in the calculated values.
