Notes. The first line block corresponds to the observational constraints used in our modelling, the second line block gives the values of the free parameters obtained, the third line block gives the assumed parameters of the models, and the fourth, provides the assumed parameters of the system originating from observations. All the models were compared using χ2 defined as the sum of the squared relatives differences between the observed constraints and the models.
