Histograms of the electrons plasma parameters derived by (top) statistical moments and by (bottom) fitting analysis of 1000 simulated plasma samples of plasma with n = 75 cm⁻³ and V_th = 2050 km s⁻¹. In our simulations, we assume that the number of counts follows the Poisson distribution. In each panel, we show the standard deviation of the histogram, which we consider as the typical statistical error for the corresponding parameter. Those are used as error bars in Figures 8 and 9.
