VizieR Online Data Catalog: Reliable open cluster candidates from Gaia EDR3 (Chi+, 2023)
Abstract
In this study, we refer to the study of Li+ (2022, J/ApJS/259/19) to obtain a data set of open cluster (OC) candidates using the FoF algorithm. We then present an improved hybrid algorithm to identify OCs from OC candidates found by FoF more robustly.
After obtaining the 801 OC candidates, we crossmatched our candidates with published OC catalogs. See Section 3.2. After isochrone fitting, we classified the OC candidates based on their CMD morphologies and isochrone fitting results to facilitate our manual visual inspection. See Section 3.4. Among the 80 candidates (class A and class B), 46 candidates were finally considered as possible real OCs (see Table 2). Some of these 46 candidates are shown in Figure A2 in the Appendix.
