cds-question@unistra.frasteroidsSelection have been made of asteroids-asteroids close encounters inducing perturbations large enough to deduce masses of perturbing objects. In tablea1.dat, and tablea3.dat, the epoch of encounters is given as well as the impact parameter, the relative distance and the criterion of maximum deflection (see section 2). The epoch of encounters is defined as the epoch when the relative distance or velocity between the two asteroids become minimum or the criterion of deflection becomes maximum. The ({Delta}{alpha},{Delta}{delta}) given in tables are the maximum differences in right ascension and declination between the perturbed and the unperturbed orbits and the epoch of maximum ({Delta}{alpha},{Delta}{delta}) is defined as the mean epoch for the maximum values of ({Delta}{alpha},{Delta}{delta}). Finally, in tablea2.dat and tablea4.dat, we give the observability of each encounters. We give the periods when the asteroids have a mean solar elongation greater than 50 degrees and when the perturbations of the orbits induced by the Multiple Gravitational Event (MGE) are greater than 50 mas. Mean values of these perturbations in right ascension and declination computed over the corresponding periods are given in Columns 4 and 5.2003A&A...406..751Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/406/751CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/406/751https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/406/751http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/406/751https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/406/751https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/406/751http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/406/751GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+A/406/751/tablea1Multiple MGE (Multiple Gravitational Event) detected from 2003 to 2022 inducing perturbations of orbits in right ascension and declination greater than 50mas.recnoRecord number assigned by the VizieR team.
