cds-question@unistra.fropen-star-clustersinfrared-photometryvisible-astronomyproper-motionstrigonometric-parallaxUsing the photometric and kinematical data from Gaia Data Release 2, three old open clusters namely Berkeley32 (Be32), Berkeley98 (Be98), and King23 are investigated. The latter two of these clusters are poorly studied in the literature. The numbers of the most probable cluster members are 563, 260, and 114 for Be32, Be98, and King23, respectively, with membership probabilities higher than 80% and lying within the clusters limiting radii. Mean proper motions (PMs; {mu}_{alpha}_cos_{delta}_ and {mu}_{delta}_) of the clusters are determined as (-0.34{+/-}0.008, -1.60{+/-}0.006), (-1.34{+/-}0.007, -3.22{+/-}0.008), and (-0.46{+/-}0.009, -0.87{+/-}0.012)mas/yr. The errors mentioned in the PMs are the Gaussian fitting errors. The blue straggler stars (BSS) in all three old clusters were found to exhibit centralized radial distribution. The clusters' radii are determined as 9.4', 12.95', and 6.6' for Be32, Be98, and King23 using radial density profiles. Ages of the clusters determined by isochrone fitting are 4.90{+/-}0.22, 3.23{+/-}0.15, and 1.95{+/-}0.22Gyr. The errors given in the clusters ages are the internal errors. The mass function slopes are found to be flatter than Salpeter's value for all three clusters. All three clusters are found to be dynamically relaxed. Galactic orbits are derived for these clusters, which demonstrate that the studied clusters follow a circular path around the Galactic center.2021AJ....161..102Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/161/102CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/345 : Gaia DR2 (Gaia Collaboration, 2018)J/AcA/41/167 : UBV photometry in Berkeley 32 (Kaluzny+, 1991)J/A+AS/133/387 : NGC 1817 and NGC 1807 proper motions (Balaguer-Nunnez+, 1998)J/A+AS/131/89 : NGC 1750 + NGC 1758 proper motions (Tian+ 1998)J/other/BASI/29.53 : UBVI photometry in Berkeley 32 (Richtler+, 2001)J/A+A/463/789 : Blue stragglers in open clusters (Ahumada+, 2007)J/A+A/480/79 : Abundances of giants in 5 Galactic clusters (Bragaglia+, 2008)J/A+A/493/959 : UBV(RI)cHalpha photometry in omega Cen (Bellini+, 2009)J/A+A/496/441 : Radial velocities of Berkeley 32 stars (Randich+, 2009)J/MNRAS/399/2146 : Orbits of open clusters in the Galaxy (Wu+, 2009)J/A+A/523/A48 : Gaia photometry (Jordi+, 2010)J/A+A/535/A30 : Chemical abundance of 12 stars open clusters (Carrera+, 2011)J/A+A/558/A53 : MW global survey of star clusters.
