Upper panel: fits of models with different rotational broadening (solid lines, 0,5,10   km   s^-1 respectively) to an S iii and a C iii line (solid histograms) of HE 0101−2707. Lower panel: similar fits of models to Si iii-lines of EC 03591−3232. It can be clearly seen that the synthetic line profiles do not match the observed ones at all. Examples for normal fits to metal lines are given in Fig. 2.
