cds-question@unistra.frvariable-starsstellar-flaresastronomical-object-identificationA brief account is given of the problems in identifying newly discovered variable stars with already known ones. These problems are most acute in dense stellar fields, for instance, in the Pleiades. To arrive to a homogeneous coordinates system for variable stars in the Pleiades, the author has measured the coordinates for nearly 550 stars in the region centered on Alcyone. This has made it possible to obtain for the first time accurate coordinates for 165 flare stars; then, for 46 stars we have round significant errors in the published coordinates. A cross-identification table between the GCVS (Cat. <II/139>) and the catalogue of Haro et al. (1982, Cat. <II/131>) has been compiled.1993PZ.....23..141Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/PZ/23.141CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/139 : General Catalog of Variable Stars, 4th Ed.
