cds-question@unistra.fropen-star-clustersgalaxy-classification-systemsThe present paper presents a tabulation of data on all 600 Galactic open clusters for which it is currently possible to calculate linear diameters. As expected, the youngest "clusters", with ages <15Myr, contain a significant (>=20%) admixture of associations. Among intermediate-age clusters, with ages in the range 15Myr to 1.5Gyr, the median cluster diameter is found to increase with age. Small, compact clusters are rare among objects with ages >1.5Gyr. Open clusters with ages >1Gyr appear to form what might be termed a "cluster thick disk", part of which consists of objects that were probably captured gravitationally by the main body of the Galaxy.2006AJ....131.1559Vhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/131/1559CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/229 : Optically visible open clusters and Candidates (Dias+ 2002-2005)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/131/1559https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/131/1559http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/131/1559https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/131/1559https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/131/1559http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/131/1559GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/131/1559/table1 (Diameters of open clusters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/131/1559/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/131/1559/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/131/1559/table1?GETtext/xml+votable180.050000true269.975-28.18333330.0055555555555555566/474 1285 1287 1297 1302 1325 1335 1347 1377 1385 1452 1455 1457 1464 1481 1539 1583 1653 1757 1782 1783 1801 1923 1930 1948 1956 2228 2395 2436 2940 2942 2945 3011 3015 3035 3038 3045 3046 3047 3050 3052 3056 3057 3060 3061 3076 3091 3136 3153 3168 3170 3186 3230 3254 3256 3257 3259 3261 3277 3298 3302 3305 3306 3307 3308 3309 3335 3384 3556 3584 3601 3621 3622 3623 3626 3632 3633 3636 3638 3642 3644 3674 3712 3715 3724 3796 4078 4298 4698 5988 6149 6760 12042 12510 12941 12955 12990 13042 13096 13198 13309 13952 13996 14009 14013 14014 14029 14033 14059 14175 14210 14246 14251 14253 14258 14263 14295 14301 14302 14306 14310 14314 14322 14324 14336 14353 14363 14409 14415 14419 14451 14575 14603 14622 14628 14630 14643 14644 14645 14646 14650 14690 14740 14749 14752 14878 15121 15369 15376 15378 15379 15381 15388 15412 15430 15443 15478 15595 15622 15632 15662 15667 15709 15711 15749 15759 15827 16490 19693 20562 20725 20761 20797 20814 20833 20903 20957 21369 21439 21510 21517 21518 21519 21523 21529 21531 21538 21540 21548 21549 21552 21557 21560 21586 21633 21647 21656 21679 21682 21719 21774 22021 22037 22038 22056 22065 22111 22123 22130 22199 22208 22215 22216 22224 22239 22245 22246 22249 22254 22433 22478 22499 22862 22871 22885 23410 23538 23569 23580 23612 23620 23632 23633 23637 23638 23645 23696 23717 23745 23761 23769 23861 23906 23964 23982 24057 24121 24228 24266 24291 24329 24330 24333 24344 24345 24476 24489 24491 24510 24522 24544 26300 28480 28711 28800 28803 28806 28807 28809 28812 28818 28822 28825 28828 28867 28868 28890 28894 28913 28916 29027 29032 29081 29082 29101 29106 29113 29116 29269 29463 29506 29510 29513 29523 29533 29728 29779 30208 30215 30221 30222 30232 30256 30269 30308 30329 30335 30439 30506 30635 30653 31756 31790 31812 31865 32087 33099 33589 34540 37012 37211 37230 37231 37237 37245 37247 37320 37332 37333 37334 37337 37340 37343 37348 37351 37364 37375 37592 37659 37705 37708 37711 37712 37718 37719 37721 37724 37733 37744 37745 37753 37789 37790 37839 37841 37859 37865 37867 37870 37892 37895 37897 37901 37904 37920 37922 37924 37926 37929 37932 37933 37934 37938 37971 38016 38018 38024 38026 38040 38041 38073 38242 38432 38561 39131 39154 39181 39224 39233 39236 39237 39244 39245 39251 39257 39259 39274 39279 39283 39290 39356 39373 39374 39375 39384 39385 39409 39413 39417 39697 39710 39711 39714 39739 39754 39756 39762 39766 39770 39774 39775 39776 39796 39797 39801 39803 39804 39805 39806 39831 39832 39874 39883 39889 39895 39906 39907 39920 39930 39931 39956 39969 40064 40071 40101 40104 40106 40480 40490 40601 40610 40618 40620 40696 41445 41461 41466 41558 41577 41599 41613 41620 41622 41629 41646 41649 41669 41670 41672 41675 41678 41682 41688 41697 41698 41699 41703 41710 41758 41768 41770 41789 41809 41823 41834 41846 41856 41863 41878 41928 42135 42147 42153 42154 42155 42159 42163 42166 42170 42177 42202 42203 42206 42209 42213 42214 42216 42227 42268 42274 42303 42367 42374 42376 42377 42378 42394 42395 42399 42402 42420 42436 42438 42458 42462 42464 42500 42528 42583 43017 43022 43024 43033 43040 43044 43047 43048 43140 43301 45203 48947https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/131/1559?format=asciiOpticaldefaultJ/AJ/131/1559/table1Diameters of open clusterslogT?
