cds-question@unistra.fropen-star-clustersastrometryThe first Gaia Data Release contains the Tycho-Gaia Astrometric Solution (TGAS). This is a subset of about 2 million stars for which, besides the position and photometry, the proper motion and parallax are calculated using Hipparcos and Tycho-2 positions in 1991.25 as prior information. We investigate the scientific potential and limitations of the TGAS component by means of the astrometric data for open clusters. Mean cluster parallax and proper motion values are derived taking into account the error correlations within the astrometric solutions for individual stars, an estimate of the internal velocity dispersion in the cluster, and, where relevant, the effects of the depth of the cluster along the line of sight. Internal consistency of the TGAS data is assessed. . Values given for standard uncertainties are still inaccurate and may lead to unrealistic unit-weight standard deviations of least squares solutions for cluster parameters. Reconstructed mean cluster parallax and proper motion values are generally in very good agreement with earlier Hipparcos-based determination, although the Gaia mean parallax for the Pleiades is a significant exception. We have no current explanation for that discrepancy. Most clusters are observed to extend to nearly 15 pc from the cluster centre, and it will be up to future Gaia releases to establish whether those potential cluster-member stars are still dynamically bound to the clusters. The Gaia DR1 provides the means to examine open clusters far beyond their more easily visible cores, and can provide membership assessments based on proper motions and parallaxes. A combined HR diagram shows the same features as observed before using the Hipparcos data, with clearly increased luminosities for older A and F dwarfs.2017A&A...601A..19Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/601/A19CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/337 : Gaia DR1 (Gaia Collaboration, 2016)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/601/A19https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/601/A19http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/601/A19https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/601/A19https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/601/A19http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/601/A19GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/601/A19/tabled (Identifiers, positions and distance moduli for members of the clusters (tables D1-D19))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/601/A19/tabled?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/601/A19/tabled?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/601/A19/tabled?GETtext/xml+votable180.050000true53.209423.6920.0055555555555555565/112 114-115 118 121 124 442 784 786 1171 1174 3514 4122 5382 5514 5881 7120-7121 7177 7180 7953 9307 9328 9398 9404 9447 9483 9838 9934 6/272 309 311 320 322-323 325 333 336-338 341 348-350 353 357 361 365-368 373 375 382-383 437 443 452 454-455 464 466-467 478 480-481 483 489 492 494 500 504 506-507 509 836 839 1024-1026 1032 1042 1045 1052 1058 1075 1211 1717 1725-1727 1737 1739 1742 1752 1760 1762-1766 1772 1774 1776 1778 1784 1786-1787 3091-3093 3095 3099-3101 3103 3120 3127 3140 3142 3152 3160 3168 4335 4678-4679 4691 4702 4705 4709-4710 4713 4720-4722 4724-4725 4727 4805 10403 10787 14050 14053 14061 15424 16435 16437 16445 16447 16480-16481 16533 16541 16543 16577 16584 21365-21367 21373 21375 21517 21519 21523 21532-21534 21553 21555-21556 21558 22026 22049 22052 22062 22144 22146-22148 23017 23286 23313 23321 23329 23450 23454 23478-23479 23489 23497 23501-23504 23511 23518 23529 23533-23535 23537-23539 23542 23544-23545 23547-23548 24068 24099 24104 24192 24194-24195 24201 24207 24209 24211 24218 24232 24234 24248 24251 28092-28094 28108 28116 28123 28128 28131 28137 28142 28416 28433 28437 28439 28442 28445-28447 28489 28494 28496 28499 28515 28537 28560 28565 28687 28698 28707 28713 28716-28718 28728-28730 30443 30446-30447 30458 31782 31785 31787-31790 31810 31820-31821 31876-31877 37179 37183 37211 37215 37223 37227 37235 37238 37240 37242 37246 37267 37269 37271 37276 37279 37316-37318 37320-37321 37325 37328 37331 37349 37499 37573 37575 37583 37585-37588 37590 37596 37598 37605 37607 37683 37775-37776 37781-37783 37785 37787 37798 37809 37811-37813 37821 37838 37865 37922 37926-37927 37929 37931 37938-37940 37944-37946 38017 38021 39174-39175 39180-39181 39183 39186 39188-39189 39191-39193 39205 39310 39322 39337 39340 39343 39347 39392 39685-39686 39696-39698 39702 39705 39708 39730-39732 39740 39742-39743 39815 39824-39825 39828 398311.9867573869263685e-19 3.916500758235022e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/601/A19?format=asciidefaultJ/A+A/601/A19/table1Open cluster names and identifiersSimbadNameSimbad column added by the CDSmeta.idcharrecnoRecord number assigned by the VizieR team.
