Comparison of two intensity calculations. This is done by comparing (1) the intensity variation calculated using a fine wavelength grid and Voigt function for each line and (2) the intensity variation obtained by folding the intensity variation of (1) by a Gaussian slit function of 2.5 A half-half width, for the Benesov meteoroid. The abscissa is wavelength in Angstrom and the ordinate is the radiation intensity in W/(cm² − μm-sr). The flight altitude, flight velocity, nose radius, and spallation factor are the same as in Fig. 9.
