Observed light curves of meteors without spectra (diamond and triangle symbols) and best fit model light curves (solid curves). Blue corresponds to the Kunžak station and red to the Ondřejov station. The plots are titled with the meteor designation; v means initialvelocity, z is zenith distance. Parameters of best fit models are: initial mass m, luminous efficiency τ, and mean diameter of iron drops D_dr. The big letter (A, B, C, D, E or F) followed by a number means light curve class and quality of the fit (see Sect. 5).
