A comparative analysis of the D-criteria used to determine genetic links of small bodies

Description
Summary:In this article the D-criteria, which can be used to determine the genetic relationships of small bodies with their parent bodies in the solar system, are estimated. Drummond (1981), Southworth and Hawkins (1963), Jopek (1993), dynamic (Kalinin and Kulikova, 2007; Holshevnikov and Titov, 2007) D-criteria were analysed. It was found that the Drummond criterion is less sensitive to errors of observations and its upper limit does not exceed 0.2. The Southworth–Hawkins and Jopek D-criteria are more stable and have good convergence. Limiting values, which vary in the range of 0.3–0.6 (except for the Lyrids), were determined on the basis of the analysis of six meteor showers for the Southworth–Hawkins and Jopek criteria.
