Dataset for "Revealing the Extended Stellar Structure of NGC~5617--Trumpler~22 with Gaia DR3"

This dataset provides the Gaia DR3 candidate member catalogue for the NGC 5617–Trumpler 22 binary open cluster system. It contains astrometric, photometric, and radial-velocity information, as well as DBSCAN-based structural labels for the selected sources. The catalogue includes stars associated with the two cluster cores, halo population, and three spatially detached substructures. The dataset is intended to support the analysis of the extended stellar structure, spatial substructures, and internal kinematics of the NGC 5617–Trumpler 22 system.
