Fig. 3


Normalized average line profiles of Si ii, C iv, N v, and Ne viii. The observed spectra in QS and CH are shown as the diamonds and asterisks. The solid lines are single-Gaussian (lefthand panels) or multi-Gaussian (righthand panels) fitting results in network (red) and internetwork regions (black). We shift the profiles in QS network, QS internetwork and CH network regions in the y-axis by 0.04, 0.03, and 0.01, respectively, to avoid the overlap between the different spectra.
