Notes. The meaning of the different columns is ID, RA, Dec: YMCA identifier and the coordinates of the SCs; R: estimated radius; log t: logarithm of the age; Nstars: number of stars within the SC radius; G: value of the parameter defined in Eq. (2); n0 central number surface density as derived from the fit of the radial density function (Eq. (3)); rc estimated core radius expressed in arcmin and parsec (Eq. (4)); Tile: tile in which each SC resides; Flag: robustness ranking of SC: A and B represent the highest and the intermediate confidence level; C reports SCs which necessitate deeper follow-up images to be confirmed. The last column reports additional IDs of already catalogued SCs as reported in SIMBAD Astronomical Database. (*): ID numbers begin from 49 since SCs from YMCA-0001 up to YMCA-0048 were presented in Gatto et al. (2020). To properly match the position of the stars in the CMD of NGC 2257 (YMCA-0070), we adopted Z = 0.0006 and a distance modulus of DM = 18.37 mag, as reported in Milone et al. (2023).
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.
