Notes. D – Distance of the galaxy from Earth; re – Effective radius; M – Stellar mass of the galaxy; ν – Sérsic index; rM – MOND transitional radius; θ – Parameter defined by Eq. (18); Vc – Asymptotic circular velocity; Ve,n – Asymptotic expansion velocity of the nth shell; r10,c – Minimum large-enough radius for measuring the asymptotic circular velocity; r10,e – Minimum large-enough radius for measuring the asymptotic expansion velocity; N( >r10,c) – Number of shells suitable for verifying the baryonic TF relation; N( >r10,e) – Number of shells suitable for verifying the mass vs. shell expansion velocity relation.
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.
