Z | kpc | X coordinate in the Galactocentric coordinate system. Sun is at ( − 8.122, 0.0, 0.0208) kpc. | float |
pmra | mas yr−1 | Proper motion in RA of cluster centre multiplied by cos(δ), as given in Cantat-Gaudin et al. (2020). | float |
pmdec | mas yr−1 | Proper motion in declination of cluster centre, as given in Cantat-Gaudin et al. (2020). | float |
parallax | mas | Parallax of cluster centre as given in Cantat-Gaudin et al. (2020). | float |
radial_velocity | km s−1 | Radial velocity of cluster centre from Simbad. | float |
radial_velocity_source | – | Source of radial velocity. | str |
age | Myr | Age of the cluster from Cantat-Gaudin et al. (2020). | float |
n | – | Number of stars calculated as the sum of all membership probabilities. | float |
n_members | – | Number of stars with reported membership probability. | int |
n_members_50 | – | Number of stars with membership probability > 0.5. | int |
n_members_90 | – | Number of stars with membership probability > 0.9. | int |
galaxia_com | – | Mean completeness (NGaia/NGalaxia) in the region of the cluster. | float |
A_G | mag | Mean extinction in G band for stars with membership probability > 0.5 calculated using extinctions in Gaia DR3. | float |
mass_func_index | – | Index of the power law of the mass function (α). | float |

radial_velocity_std | km s−1 | Standard deviation of the radial velocities of all stars used to measure radial_velocity_measured. | float |
Notes. The table lists all the analysed clusters.
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.
