The dataset for following AstDyS release dates is available:
2009 Feb (the release used in the paper Pravec and Vokrouhlicky mentioned above)

Descriptions of columns in the file linked above:
d, sigma(d) - distance of orbits of pair members and its standard error in the 5-dimensional space of osculating orbital elements,
d_prop -distance of pair members in the 3-dimensional space of proper orbital elements,
a, e, i, H_1, H_2, dH - esculating semimajor axis, eccentricity, and inclination of the first asteroid of the pair, the absolute magnitudes of the pair members, and their difference, data from AstDyS,
N_1, N_1/2, N_1/4 - number of orbits with H < H_2 + 0.5 in the three nested boxes around the candidate pair,
P_1/2, P_1/4 - the computed probability that there are N_1/2, N_1/4 or more orbits in the middle and the small nested box, respectively, assuming a uniform distribution of orbits in the largest box,
R_0 - the radius of a hypersphere with specific volume (it is a characteristic distance between objects for the observed orbit density around the asteroid pair),
N(zone) - total number of asteroids (> 1-opp, H < H_2 + 0.5) in the zone of the main belt where the pair is located,
N_p - number of pairs with normalized distances < d/R_0, H < H_2 + 0.5 in the pair's zone,
z - zone code: 1, 2, 3 are the inner, central, and outer main belt, 4 is the Cybele zone, 5 is the Hilda zone, and 6 is the Hungaria zone,
Ast_1, Ast_2 - designations of the brighter and fainter members of the pair,
Remark - on the long-term dynamics of the pair.
