Extended Data Fig. 3: Size distribution of the sample particles.
From: Electrical charging overcomes the bouncing barrier in planet formation

The black dots show a histogram of the measured grain sizes of the glass particles used. The uncertainties in size determination of individual grains are 2 %. The blue line is a normal distribution fitted to the experimental data. From the fit we get an average grain diameter of 434 µm with the standard deviation of ± 17 µm.
