cds-question@unistra.fropen-star-clustersradial-velocityproper-motionsWe present and analyse the kinematics and orbits for a sample of 488 open clusters (OCs) in the Galaxy. The velocity ellipsoid for our present sample is derived as ({sigma}(U),{sigma}(V),{sigma}(W)) = (28.7, 15.8, 11.0)km/s which represents a young thin-disc population. We also confirm that the velocity dispersions increase with the age of a cluster subsample. The orbits of OCs are calculated with three Galactic gravitational potential models. The errors of orbital parameters are also calculated considering the intrinsic variation of the orbital parameters and the effects of observational uncertainties. The observational uncertainties dominate the errors of derived orbital parameters. The vertical motions of clusters calculated using different Galactic disc models are rather different. The observed radial metallicity gradient of clusters is derived with a slope of b=-0.070+/-0.011dex/kpc. The radial metallicity gradient of clusters based on their apogalactic distances is also derived with a slope of b=-0.082+/-0.014dex/kpc. The distribution of derived orbital eccentricities for OCs is very similar to that derived for the field population of dwarfs and giants in the thin disc.2009MNRAS.399.2146Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/399/2146CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/ocl : Optically visible open clusters and Candidates (Dias+ 2002-2010)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/399/2146https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/399/2146http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/399/2146https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/399/2146https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/399/2146http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/399/2146GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/399/2146/clusters (All parameters of clusters: positions, velocities, and orbital parameters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/399/2146/clusters?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/399/2146/clusters?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/399/2146/clusters?GETtext/xml+votable180.050000true0.5583367.416670.0055555555555555566/463 1285 1287 1297 1302 1304 1325 1347 1457 1464 1482 1539 1582 1717 1923 1930 2228 2395 2436 2859 2940 2942 2971 3004 3009 3011 3037-3038 3045 3055 3058 3138 3230 3254 3256-3257 3259 3262 3274 3283 3301 3306-3308 3317 3362 3384 3556 3595 3597 3604 3622 3632 3638 3681 3712 3755 3796 4078 4298 4698 6149 6691 6760 12941 12955 12962 12985 12990 13042 13096 13198 13304 13565 14029 14033 14056 14059 14070 14154 14175 14210 14229 14233 14246 14256 14263 14265 14295 14301 14314 14320 14322 14353 14356 14410 14415 14419 14436 14523 14571 14575 14603 14624 14628-14630 14642-14643 14645-14646 14653 14690 14749 14752 14878 15121 15376 15396 15412 15430 15443 15445 15449 15478 15595 15622 15653 15661-15662 15667 15683 15693 15711 16490 20562 20755-20756 20797 20903 20957 21367 21369 21438-21439 21510 21517 21522-21523 21529 21531 21538 21549 21557 21561 21586 21633 21643 21647 21656 21658 21682 21774 22058 22112 22121 22123 22130 22208 22219 22222 22239 22246 22249 22253-22254 22263 22433 22499 22805 22854 22862 22871 22880 22887 22892-22893 22895 22993 23007 23410 23569 23580 23632-23633 23637 23641 23717 23745 23769 23861 23982 24026 24095 24121 24228 24266 24291 24330 24333 24340 24344-24345 24489 24510 24522 28481 28711 28745 28800 28803 28806-28807 28809 28812 28818 28822 28833 28838 28868 28891-28892 28894 28913 28916-28917 29027 29032 29035 29081-29082 29088 29092 29095 29106 29113 29116 29166 29269 29456 29460 29463 29509 29513 29523 29533 29619 29728 30127 30208 30215 30256 30335 30439 30540 30635 30653 31070 31756 31790 31812 31865 33099 34495 37012 37120 37230-37231 37237 37245 37247 37332-37334 37341 37348 37351 37592 37659 37705 37712 37719 37721 37733 37745 37789-37790 37839 37859 37865 37867 37886 37892 37895 37897 37901 37904-37905 37912-37913 37920 37923 37926 37929-37930 37932-37933 37938 37971 38016 38018 38021 38024 38026 38051 38073 38242 38432 38561 38627 39131 39154 39179 39181 39233 39243-39245 39251 39254 39259 39283 39288 39294 39354 39356 39374-39375 39384 39386 39417 39697 39714 39739 39762 39766 39770 39775-39776 39785 39795 39801 39804-39806 39832 39874 39879 39883 39894 39901 39907 39912 39920 39930-39931 39956 40101 40104 40106 40490 40620 40696 41443 41445 41461 41559 41577 41599 41610 41613 41615 41620 41629 41633 41646 41653 41669-41670 41677 41682 41688 41692 41696 41699 41703 41707 41710 41747 41750 41758 41770 41789 41834 41856 41863 41867 41995 42029 42135 42147 42153 42155 42166 42203 42207 42209 42213 42216 42227 42268 42274 42303 42367 42374 42376 42394-42395 42399 42402 42417 42458 42464 42470 42486 42500 42583 43011 43022 43024 43027 43033 43036 43044 43048 43301 47621 47858https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/399/2146?format=asciiOpticaldefaultJ/MNRAS/399/2146/clustersAll parameters of clusters: positions, velocities, and orbital parametersAge?
