The validity of the derived distance scale is corroborated by the Hipparcos trigonometric parallaxes of seven clusters. The age distribution of the clusters is distorted by observational selection, which is enhanced with increasing heliocentric distance and which is virtually independent of interstellar extinction. As a result, the youngest (logt&lt;=7.5) clusters are represented almost exclusively at heliocentric distances &gt;2kpc, and the mean age of the cataloged clusters with logt&lt;=100Myr decreases from 50Myr in the solar neighborhood down to 15Myr at heliocentric distances &gt;2.4kpc.</description><source format="bibcode">1999PAZh...25...10D</source><referenceURL>https://cdsarc.cds.unistra.fr/viz-bin/cat/J/PAZh/25/10</referenceURL><type>Catalog</type><contentLevel>Research</contentLevel><relationship><relationshipType>IsServedBy</relationshipType><relatedResource ivo-id="ivo://CDS.VizieR/TAP">TAP VizieR generic service</relatedResource></relationship><relationship><relationshipType>IsServedBy</relationshipType><relatedResource>Conesearch service</relatedResource></relationship><relationship><relationshipType>related-to</relationshipType><relatedResource ivo-id="ivo://CDS.VizieR/J/other/A+AT/25.185">J/other/A+AT/25.185 : Globular clusters absolute proper motions (Dambis, 2006)</relatedResource><relatedResource>http://www.univie.ac.at/webda : WEDBA Home Page</relatedResource></relationship></content><rights>https://cds.unistra.fr/vizier-org/licences_vizier.html</rights><capability><interface xsi:type="vr:WebBrowser"><accessURL use="full">https://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/PAZh/25/10</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/PAZh/25/10</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/PAZh/25/10</mirrorURL></interface></capability><capability><interface xsi:type="vs:ParamHTTP"><accessURL use="base">https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/PAZh/25/10</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/votable?-source=J/PAZh/25/10</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/PAZh/25/10</mirrorURL><queryType>GET</queryType><resultType>text/xml+votable</resultType></interface></capability><capability standardID="ivo://ivoa.net/std/TAP#aux"><interface xsi:type="vs:ParamHTTP" role="std"><accessURL use="base">https://tapvizier.cds.unistra.fr/TAPVizieR/tap</accessURL></interface></capability><capability xsi:type="cs:ConeSearch" standardID="ivo://ivoa.net/std/ConeSearch"><description>Cone search capability for table J/PAZh/25/10/table1 (Parameters of open clusters)</description><interface xsi:type="vs:ParamHTTP" role="std"><accessURL use="base">https://vizier.cds.unistra.fr/viz-bin/conesearch/J/PAZh/25/10/table1?</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/conesearch/J/PAZh/25/10/table1?</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/conesearch/J/PAZh/25/10/table1?</mirrorURL><queryType>GET</queryType><resultType>text/xml+votable</resultType></interface><maxSR>180.0</maxSR><maxRecords>50000</maxRecords><verbosity>true</verbosity><testQuery><ra>65.15</ra><dec>44.91667</dec><sr>0.005555555555555556</sr></testQuery></capability><coverage><spatial>6/463 1287 1297 1325 1335 1653 2940 2942 3045 3047 3138 3254 3256 3257 3302 3307 3384 3584 3622 3623 3632 3642 3724 5988 12941 12990 14210 14253 14258 14263 14295 14301 14302 14322 14353 14415 14419 14603 14628 14630 14643 14645 14646 14690 15381 15430 15443 15478 15622 15632 15662 20755 21439 21510 21517 21529 21633 21647 21682 22021 22058 22123 22208 22219 22249 23637 23769 23962 23982 24228 24333 24345 24510 26300 28800 28806 28809 28812 28891 28894 28913 28916 29027 29032 29081 29113 29463 29513 29523 29533 30208 30256 30335 30635 30653 31756 31790 37231 37333 37334 37351 37364 37375 37592 37705 37719 37721 37753 37790 37839 37865 37895 37897 37901 37924 37926 37929 37932 37938 38016 38018 38024 38026 39181 39233 39236 39244 39251 39259 39283 39355 39374 39417 39739 39754 39774 39776 39796 39801 39804 39806 39883 39907 39920 39930 39931 40106 40610 41445 41461 41646 41670 41675 41682 41696 41699 41710 41758 41770 41856 41863 41878 41928 42152 42153 42166 42202 42203 42209 42213 42227 42303 42367 42376 42377 42394 42395 42402 42420 42458 42500 43024 43033 43044 43047 43048</spatial><footprint ivo-id="ivo://ivoa.net/std/moc">https://cdsarc.cds.unistra.fr/viz-bin/moc/J/PAZh/25/10?format=ascii</footprint><waveband>Optical</waveband></coverage><tableset><schema><name>default</name><table><name>J/PAZh/25/10/table1</name><description>Parameters of open clusters</description><column><name>e_DM0</name><description>Error of true distance modulus</description><unit>mag</unit><ucd>stat.error</ucd><dataType xsi:type="vs:VOTableType">float</dataType></column><column><name>recno</name><description>Record number assigned by the VizieR team.
