THEODOR code was used to derive the heat flux from the IR surface temperature data in the presence of co-deposited layers. We observe that ELMs are composed of filaments with toroidal mode number between 5 and 15. Although not an ELM phenomena, an observation of strike point splitting in extremely low density L-mode plasmas will also be presented, believed to be due to field line ergodisation, probably due to mode activity.
