Relationships between the delay time ΔT and the mean growth rates dV X/dt (a), dB Z/dt (b), and dE KL/dt (c) based on the analysis of coordinated events. Thin vertical bars present the standard deviation (sd) of individual values ΔV XT, ΔB ZT, and ΔE KLT from their mean quantities in each ΔT group; thick vertical bars present the standard error of the mean quantity determination
