Figure 2.

Dependence of the ${\chi }_{\mathrm{red}}^2$ function around its minimum (${\chi }_{\mathrm{red},\min }^2$ ≃ 60.8) on a given free parameter P . P_min is the value of the parameter P derived from the best fit. The parameter x(R_⋆ ≤ r ≤ R_in) is plotted in solid black (●), x(r = R_out) in dashed black (○), T_rot(R_in) in solid cyan (*), T_rot(R_out) in dashed cyan (*), T_{vib,v = 1 – 0}(R_⋆) in solid red (■), T_{vib,v = 1 – 0}(R_in) in dashed red (□), T_{vib,v = 1 – 0}(R_out) in dotted red (⋄), T_{vib,v = 2 – 1}(R_⋆) in solid green (▲), T_{vib,v = 2 – 1}(R_in) in dashed green (△), T_{vib,v = 2 – 1}(R_out) in dotted green (▽), T_{vib,v = 3 – 2}(R_⋆) in solid blue (×), T_{vib,v = 3 – 2}(R_in) in dashed blue (×), and T_{vib,v = 4 – 3}(R_⋆) in dotted blue (+). See the caption of Tables 1 and 2 for the definitions of these parameters.
