cds-question@unistra.freclipsing-binary-starsphotometryStromgren b,y photometry of the detached A-type eclipsing binary EG Serpentis was obtained. Combined with the radial velocity curves in Popper [PASP, 98, 1312 (1986)], it was used to determine anew the system's parameters using the Wilson-Devinney code. The age of the system is derived from a comparison with the Bertelli et al. [A&AS, 85, 845 (1990)] isochrones. Within the accuracy limits, the results are in accordance with expectations.1993AJ....105.2291Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/105/2291CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/105/2291https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/105/2291http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/105/2291https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/105/2291https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/105/2291http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/105/2291GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/AJ/105/2291/table1ObservationsrecnoRecord number assigned by the VizieR team.
