Notes. Ψ is defined as Ψ = (M/L)dyn/(M/L)pop. The third-to-last column denotes the literature source of the original measurement of Mdyn,remod, and the origin of the [Fe/H] value. lit = 1: Cen A UCDs from Mieske et al. (2008), based on original measurements presented in Rejkuba et al. (2007). lit = 2: Virgo UCDs from Mieske et al. (2008), based on original measurements presented in Haşegan et al. (2005). lit = 3: Virgo UCDs from Evstigneeva et al. (2007). lit = 3.2: the Virgo UCD M59cO from Chilingarian & Mamon (2008). lit = 3.5: Fornax UCDs from Hilker et al. (2007). lit = 7: CenA UCDs from Taylor et al. (2010), largely based on a re-reduction of data published in Rejkuba et al. (2007). lit = 8: Fornax UCDs from Chilingarian et al. (2011), doing a remeasurement and re-modelling of spectroscopic data from Mieske et al. (2008). For objects marked with an asterisk ∗, no unique King profile fit is available in the literature. Composite or single Sérsic fits are adopted, see Sect. 2.1 for details. For F19, the indicated King profile parameters rc and c is for the core component. For F19, the small error bar of 0.3 km s-1 for the measured velocity dispersion is due to the very high S/N spectrum obtained for this object, combined with the usage of the full spectral fitting technique (Chilingarian et al. 2011).
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.
