Notes. The different columns correspond to the scaling parameter b, the ratio bm = Re/h, the central surface brightness I0, the central luminosity density ν0, the central value of the gravitational potential Ψ0, the central velocity dispersion σ0, and the central projected velocity dispersion σp, 0. All quantities are given in dimensionless units, or equivalently, for a model with Re = L = M = 1.
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.
