VizieR Online Data Catalog: 628 new open clusters found with OCfinder (Castro-Ginard+, 2022)
Abstract
The methodology developed to search for new OCs in Gaia data, OCfinder, is described in detail in Paper I (Castro-Ginard et al., 2018A&A...618A..59C, Cat. J/A+A/618/A59. It was successfully applied to detect 23 new nearby OCs (Castro-Ginard et al.,2018A&A...618A..59C, Cat. J/A+A/618/A59) in the TGAS data set of Gaia DR1. It was also applied to Gaia DR2 where 53 new OCs were detected in a direction near the Galactic anticentre (Castro-Ginard et al. 2019) and hundreds of new OCs in a big data search on the whole Galactic disc (Castro-Ginard et al., 2020A&A...635A..45C, Cat. J/A+A/635/A45).
Table 1 contains mean astrometric parameters for the detected clusters. Table 2 contains the member stars found for the new UBC open clusters reported in the paper. The columns are for astrometric parameters for the member stars, i.e. positions, parallax, proper motions and radial velocity when available, as well as the photometric information in the G, GBP and GRP bands. It also includes the Gaia source_id to allow the cross-match with other catalogues. (2 data files).- Publication:
