Material strength classification of the JEO meteoroids (open circles) based on the K_B (left) and P_E (right) parameter as a function of the Tisserand parameter relative to Jupiter. Mean K_B and P_E material strengths and their standard deviation (solid error bar) and overall dispersion (dashed error bar) for different meteoroid streams from Matlovič et al. (2019) are displayed for comparison. Sizes of meteoroid marks reflect relative meteoroid masses in logarithmic scale.
