VizieR Online Data Catalog: Star cluster systems Collinder 135 and UBC 7 (Ishchenko+, 2024)
Abstract
We acquire the deep census of the two closely situated open clusters Collinder 135 and UBC 7 based on Gaia DR3 data. We do a search in the broad vicinity of the clusters to recover evolutionary related sources, and recover an extended coeval and comoving population forming an extended surrounding stellar halo. In the catalogue we provide the list of sources selected as members to the system of Collinder 135 and UBC 7 (including stellar halo) with membership probability larger than 60%, along with basic information from Gaia DR3 (sourceid, l, b, plxerr, gmag, bpmag, rpmag), recalculated (plx_corr is the Gaia EDR3 parallax with parallax zero-point correction according to Lindegren et al. (2021A&A...649A...4L), pml and pmb for proper motion in l and b), calculated (membership probability MP) characteristics and a flag of affiliation F to one of the clusters of to halo (1 for members of Collinder 135, 2 for UBC 7, 0 for halo).
