We found that all the clusters are older than the Hyades, with ages ranging from 0.8Gyr (NGC 6827 and Berkeley 5) to 4.0Gyr (Berkeley 56). The latter is one of the old open clusters with the largest heliocentric distance.2006MNRAS.371.1301Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/371/1301CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/371/1301https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/371/1301http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/371/1301https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/371/1301https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/371/1301http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/371/1301GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/371/1301/ber5 (Berkeley 5 CCD BVI photometry)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/371/1301/ber5?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/371/1301/ber5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/371/1301/ber5?GETtext/xml+votable180.050000true27.100771762.86916750.005555555555555556Cone search capability for table J/MNRAS/371/1301/ber44 (*Berkeley 44 CCD BVI photometry)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/371/1301/ber44?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/371/1301/ber44?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/371/1301/ber44?GETtext/xml+votable180.050000true289.317754419.54599310.005555555555555556Cone search capability for table J/MNRAS/371/1301/ber52 (Berkeley 52 CCD BVI photometry)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/371/1301/ber52?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/371/1301/ber52?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/371/1301/ber52?GETtext/xml+votable180.050000true303.571893328.89148580.005555555555555556Cone search capability for table J/MNRAS/371/1301/ber56 (Berkeley 56 CCD BVI photometry)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/371/1301/ber56?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/371/1301/ber56?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/371/1301/ber56?GETtext/xml+votable180.050000true319.370117241.86389280.005555555555555556Cone search capability for table J/MNRAS/371/1301/ngc6827 (NGC 6827 CCD BVI photometry)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/371/1301/ngc6827?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/371/1301/ngc6827?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/371/1301/ngc6827?GETtext/xml+votable180.050000true297.240588321.18537280.005555555555555556Cone search capability for table J/MNRAS/371/1301/skiff1 (*Skiff 1 CCD BVI photometry)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/371/1301/skiff1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/371/1301/skiff1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/371/1301/skiff1?GETtext/xml+votable180.050000true14.502777268.48140220.0055555555555555566/3636 3638 3743 12978 12984 13055 13989 32089https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/371/1301?format=asciiOpticalInfrareddefaultJ/MNRAS/371/1301/ber5Berkeley 5 CCD BVI photometryrecnoRecord number assigned by the VizieR team.
