Values of spin parameters as a function of rotation frequency determined through three different methods. In pink are plotted the values computed with ACOR on the stellar model 2 m (see Sect. 3.2), the violet curves correspond to values computed in the truncated convective core of model 2 m (see Sect. 4.2), and the grey constant lines stand for the homogeneous spherical box case (see Sect. 2.1). These are given for dipolar retrograde modes (upper panel), zonal (middle), and prograde ones (lower panel).
