Brussel-Montreal density functional has been designed to describe accurately nuclear matter in neutron stars. Hence, the fitting was done not only using experimental nuclear data (as it is usually done) but also theoretical results for many-body calculations (for example pairing gaps).
In the following articles one can find more details about the functional family:
