Fundamental astrophysical parameters such as color excesses, photometric metallicities, ages, and isochrone distances were based on UBV-data analyses, whereas membership probability calculations, structural and astrophysical parameters, as well as the kinematic analyses were based on Gaia DR3-data. We identified 74 and 596 stars as the most probable cluster members with membership probabilities over 50% for Rup-1 and Rup-171, respectively. The color excesses E(B-V) were obtained as 0.166+/-0.022 and 0.301+/-0.027mag for Rup-1 and Rup-171, respectively. Photometric metallicity analyses were performed by considering F-G type main-sequence member stars and found to be [Fe/H]=-0.09+/-0.16 and [Fe/H]=-0.20+/-0.20dex for Rup-1 and Rup-171, respectively. Ages and distances were based on both UBV and Gaia-data analyses; according to isochrone-fitting these values were estimated to be t=580+/-60Myr, d=1469+/-57pc for Rup-1 and t=2700+/-200Myr, d=1509+/-69pc for Rup-171. The present-day mass function slope of Rup-1 was estimated as 1.26+/-0.32 and Rup-171 as 1.53+/-1.49. Galactic orbit integration analyses showed that both of the clusters might be formed outside the solar circle.2024AN....34540054Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AN/345/40054CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/350 : Gaia EDR3 (Gaia Collaboration, 2020)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AN/345/40054https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AN/345/40054http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AN/345/40054https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AN/345/40054https://vizier.iucaa.in/viz-bin/votable?-source=J/AN/345/40054http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AN/345/40054GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AN/345/40054/table (Catalogues for Rup-1 and Rup-171)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AN/345/40054/table?https://vizier.iucaa.in/viz-bin/conesearch/J/AN/345/40054/table?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AN/345/40054/table?GETtext/xml+votable180.050000true99.0201667-14.10164170.0055555555555555566/20966 291521.9867573869263685e-19 3.916500758235022e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AN/345/40054?format=asciiOpticaldefaultJ/AN/345/40054/tableCatalogues for Rup-1 and Rup-171recnoRecord number assigned by the VizieR team.
