Smoothed diagonal components of the electron thermal pressure tensor as a function of the electron number density at the DCBL in logscale, at t = 27.24 ms. P_e,th,yy and P_e,th,zz have been purposely scaled so that they do not to overlap with P_e,th,xx. Five inflexion points (blue, red, yellow, green, and cyan) have been identified, plus one (violet) for a later purpose. Their locations within the DCBL are indicated within the inset where B_z is plotted as a function of x.
