The possible presence of noise affecting the proper elements of asteroid families (due to several dynamical and also physical effects) influences the reconstruction of the original velocity fields. A noise on eccentricities alone is not sufficient to explain the observed features, and a noise on semimajor axes must also be taken into account. A preliminary quantitative evaluation of these noises on both elements is attempted.

Abstract: | The possible presence of noise affecting the proper elements of asteroid families (due to several dynamical and also physical effects) influences the reconstruction of the original velocity fields. A noise on eccentricities alone is not sufficient to explain the observed features, and a noise on semimajor axes must also be taken into account. A preliminary quantitative evaluation of these noises on both elements is attempted. |
