Examples of light curves of meteors with iron spectra. The observed light curves are black, the theoretical ones are red or blue. The dashed curves represent the radius R of the meteoroid divided by its initial value R_∞. The letters A–E represents the class of the observed light curve (see the text). Here A is meteor 09820028 from Kunžak station, B is meteor 03802071 from Ondřejov station, C is meteor 08505008 from Kunžak station, D is meteor 03504018 from Ondřejov station, and E is meteor 12815084 from Kunžak station.
