Using 
yields continuity of the curves at the extreme values (
and 
), which makes the picture clearer. On the other hand as the value of 
increases the unstable regime of 
gets smaller and the resolution for 
steps plotted should decrease. Thus, to plot these lines, we used 
which is sufficiently close to 0 to illustrate the phase transition with high accuracy in
