Beginning height of meteor as a function of speed. Different spectral classes are plotted. The solid line shows the mean beginnings of meteoroids with average strengths. The dashed lines mark their limits (±5 km). The equation of the empirical line is HB = 54v0.195. Uncertainties for beginning heights and velocities were negligible for display in the graph (for details see Table 4).
