Maps of intensity a), Doppler shift b), and line width c) of Si IV (1394 Å) for the second raster scan in the mutual-helicity phase. The dotted lines highlight the location of the two cool loops. The dashed lines a−i in a) and b) indicate the positions of the spectra shown in Fig. 5. The yellow arrow in c) marks a region with enhanced line width. The location of the maps is indicated in Fig. 1b. The FOV is 60.5″ × 33.3″.
