15. As for this terminology, the 'point' should be read as the sense of a 'numerically detectable' threshold value. In fact, as the cross-over point is dependent on the couplings j2A andd J2B, the spin magnitudes s and S, the temperature t, and the external field h, we could not obtain any analytic value of the 'true' cross-over line at finite temperature for making a comparison with our numerical results.
