Notes. The median cluster positions are listed (see Table 4 for the median velocities). In Cols. 6–12, we list the medians of the positional parameters for each cluster including all cluster members (without considering any stability cut). The given lower and upper uncertainties represent the 1σ scatter around the median. In this scatter, the original measurement uncertainties of single stellar sources are not considered.

(a)

Column 4 lists the brightest star that was selected as a member by SigMA. The star annotation “*” is used as in the SIMBAD astronomical database (Wenger et al. 2000) and helps distinguish stellar names from cluster names throughout the manuscript since some clusters are named after bright stars. Further bright stellar member candidates, which were observed by HIPPARCOS (partially not in Gaia DR3), are listed in Table 5.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
