Notes. This table (including previous page) is available at the CDS. Columns meanings: (1) UDG ID; (2) Central surface brightness in the g-band; (3) Average surface brightness within Re in the g-band; (4) Effective radius in arcsec in the g-band; (5) Effective radius in kpc in the g-band computed using the UDG distance when available, otherwise the assumed host distance is used; (6) Stellar mass computed based on the stellar mass-to-light ratios from Bell et al. (2003) and the derived (g − r)0 color using the formula log(M*/M⊙) = − 0.306 + 1.097(g − r)0 − 0.4(Mr − 4.77); (7) Halo-to-stellar mass ratio computed based on the mass ratio from Harris et al. (2017) and the derived GC count using the formula Mhalo = MGC, tot/2.9 × 10−5.
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.
