Distribution of the estimated uncertainties in RA, Dec and speed for the synthetic meteors. The length of the boxes indicates the dispersion of the data. Each box encloses 50% of the data. The extending vertical lines from the boxes indicate the range of 80% of the data with the lower and upper horizontal bars marking the 10% and 90% levels. Data outside the 80% range are shown as open circles (∘). The horizontal line inside each box indicates the median value. The units are degrees for RA and Dec, and km s⁻¹ for speed.
