Comparison between calculated and observed spectra for the Benesov meteoroid. The abscissa is wavelength in Angstrom. The ordinate in the top panel is the intensity in W/(cm² − μm-sr). The ordinate in the bottom panel is intensity in arbitrary units. The flight altitude = 78 km, velocity = 21 km s⁻¹, nose radius = 0.75 m, and spallation factor = 1. This case is unfavorable for calculation.
