Variation of velocity dispersions calculated over the whole domain in three temperature bands in the four models after kink instabilities. Model names are shown in panels. Black solid line is for the 0.25 MK <T< MK band, red dashed line is for 1 MK <T<4 MK, and blue dot-dashed line is for T> 4 MK. (There is practically no plasma with temperature >4 MK in models S1 and S2.) Lower limits of each time interval correspond approximately to the onset of kink instability and fast energy release.
