Component size ratio (R_s/R_p) is secondary radius divided by primary radius; separation (a/R_p) is expressed in terms of the radius of the primary. Some values are estimated based on assumed albedoes, densities, etc.

Component size ratio (R_s/R_p) is secondary radius divided by primary radius; separation (a/R_h) is expressed relative to the Hill radius. Some values are estimated based on assumed albedoes, densities, etc.
