Considering the stars with membership probability ($P_{\\mu}$) $> 90\\%$, we identified 676 most probable cluster members within the cluster's limiting radius. The mean proper motion (PM) for King 11 is determined as: $\\mu_{x}=-3.391\\pm0.006$ and $\\mu_{y}=-0.660\\pm0.004$ mas yr$^{-1}$. The blue straggler stars (BSS) of King 11 show a centrally concentrated radial distribution. The values of limiting radius, age, and distance are determined as 18.51 arcmin, 3.63$\\pm$0.42 Gyr and $3.33\\pm0.15$ kpc, respectively. The cluster's apex coordinates ($A=267.84^{\\circ} \\pm 1.01^{\\circ}$, $D=-27.48^{\\circ} \\pm 1.03^{\\circ}$) are determined using the apex diagram (AD) method and verified using the ($\\mu_U$,$\\mu_T$) diagram. We also obtained the orbit that the cluster follows in the Galaxy and estimated its tentative birthplace in the disk. The resulting spatial velocity of King 11 is 60.2 $\\pm$ 2.16 km s$^{-1}$. A significant oscillation along the $Z$-coordinate up to 0.556$\\pm$0.022~kpc is determined.", "revisions": [ { "version": "v1", "updated": "2021-06-09T03:06:25.000Z" } ], "analyses": { "keywords": [ "old open cluster king", "kinematic analysis", "photometric", "old age open cluster king", "clusters apex coordinates" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
