, duration of
ns, plasma density of 
, initial plasma temperature of
keV and magnetic field of
T. Each of the other six colourful curves has one of the above parameters being changed, that is, (a)
ns (red, solid), 
(blue, solid),
T (green, solid) and
T (orange, solid); (b) 
(red, dotted),
eV (blue, dotted) and 
(green, dotted).
