cds-question@unistra.fropen-star-clustersproper-motionsAbsolute proper motions, their errors and membership probabilities of 810 stars in the area of two NGC objects, NGC 1817 and NGC 1807. The Tycho-2 Catalogue is used as the reference frame, and the cross-identification is given. Parametric and non parametric membership probabilities are compared based on there being only one very extended physical cluster: NGC 1817.2004A&A...426..819Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/426/819CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/426/827 : NGC 1817 & NGC 1807 ubvyH{beta} phot.
