cds-question@unistra.fropen-star-clustersproper-motionsccd-photometryWe present techniques for obtaining precision astrometry using old photographic plates from assorted large-aperture reflectors in combination with recent CCD Mosaic Imager frames. At the core of this approach is a transformation of plate/CCD coordinates into a previously constructed astrometric reference frame around the open cluster NGC 188.2003AJ....126.2922Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/126/2922CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/124/601 : Absolute positions + proper motions in NGC 188 (Platais+, 2002)Table 1: Plates and CCD mosaic frameshttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/126/2922https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/126/2922http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/126/2922https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/126/2922https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/126/2922http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/126/2922GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/126/2922/table3 (Catalog of positions, proper motions, and BV CCD photometry in the region of open cluster NGC 188)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/126/2922/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/126/2922/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/126/2922/table3?GETtext/xml+votable180.050000true5.612864285.4824440.0055555555555555565/1019 6/4073 4075https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/126/2922?format=asciiOpticaldefaultJ/AJ/126/2922/table3Catalog of positions, proper motions, and BV CCD photometry in the region of open cluster NGC 188recnoRecord number assigned by the VizieR team.
