cds-question@unistra.frmultiple-starsWe examined the statistics of an angle gamma between the radius vector of a visual companion of a multiple star and the vector of its apparent relative motion in the system. We found that for the wide physical subsystems of the 174 objects from the Multiple Star Catalogue (MSC, Cat. <J/A+AS/124/75>) gamma is bell-shaped. Table 1 presents the separation and position angle of visual outer companions of the sample multiples, and the relative motion (since discovery) and its direction - angle gamma with its error. Positions are taken for the first epoch mostly from Washington Double Star catalogue (WDS, Cat. <I/237>) and from Hipparcos (Cat. <I/239>) or Tycho (Cat. <I/239> and <I/259>) catalogues for the second epoch. Orbital motion in inner subsystems of multiple stars is taken into account in gamma when significant. Table 2 gives the cross-identification of objects and components in different catalogues.2001A&A...380..238Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/380/238CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/237 : The Washington Visual Double Star Catalog, 1996.0 (Worley+, 1996)I/211 : CCDM (Components of Double and Multiple stars) (Dommanget+ 1994)I/239 : The Hipparcos and Tycho Catalogues (ESA 1997)I/259 : The Tycho-2 Catalogue (Hog+ 2000)J/A+AS/124/75 : Multiple star catalogue (MSC) (Tokovinin 1997-1999)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/380/238https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/380/238http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/380/238https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/380/238https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/380/238http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/380/238GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/380/238/table1 (Position parameters and angles gamma)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/380/238/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/380/238/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/380/238/table1?GETtext/xml+votable180.050000true1.42545.81670.0055555555555555566/600 725 1069 1283 1314 1453 1642 1779 1852 2076 2125 2133 2184 2536 2747 2881 3146 3198 3220 3507 3997 4640 4822 5498 5777 5895 6003 6154 6574 6628 7018 7063 7117 7992 8354 8704 8794 9419 9447 9502 9541 9767 9857 10004 10089 10096 10130 10225 10467 10741 11011 11157 11302 11306 11547 12264 12301 12303 12362 12720 13161 13336 13802 13960 14525 14647 14899 15025 15093 15166 15214 15301 15330 15482 15760 15852 16122 16302 16338 16695 16771 17058 17137 17453 17721 17955 17964 18311 19556 20022 20298 20310-20311 21538 21590 21637 21749 22637 22882 22988 24185 24303 24315 24398 24484 25074 25601 26695 26886 26924 27496 27770 28329 28687 29196 29712 29942 30269 30363 30448 30550 30558 32144 32645 32720 33340 33667 33905 34141 34953 34968 35072 35301 35842 36484 37051 37099 37170 38561 38681 38896 38985 39023 39440 39500 39562 39625 40795 40805 40904 41465 41652 41943 42034 42459 42611 43072 43430 44011 44123 44332 44550 44887 45272 45299 45583 46077 46482 46958 48299 48505 48856 49101https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/380/238?format=asciiOpticaldefaultJ/A+A/380/238/table2Objects cross-identificationrecnoRecord number assigned by the VizieR team.
