Notes. The piecewise polytrope is matched at n_match = 0.16 fm⁻³ (top lines) or at n_match = 0.32 fm⁻³ (bottom lines). Values in parentheses for the posteriors correspond to those obtained employing a unique EoS based on SLy4 until n_match.

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.
