VizieR Online Data Catalog: Membership in stellar kinematic groups (Klutsch+, 2014)

The search for new members of close young associations and SKGs was done earlier by using mainly qualitative methods, such as the Eggen's criteria (Eggen 1958MNRAS.118...65E, 1995AJ....110.2862E). To gain in objectivity, we determine the membership by means of probabilistic procedures using the kinematic properties of known SKG members (Klutsch 2008, Ph.D. thesis, Observatoire de Strasbourg, France; Klutsch et al. in Highlights of Spanish Astrophysics VI, eds. M.R. Zapatero Osorio, J. Gorgas, J. Maiz Apellaniz, J. R. Pardo, & A. Gil de Paz, p. 534). We tried different methods to handle kinematic data, and we succeeded to develop two independent procedures (CES and M2M) to be able to identify new candidates of five young MGs. We widely used n-dimensional normal Gaussian distributions to determine the kinematic membership probabilities of each stellar candidate
