Examples of fitting intensity profiles Fe XIV line observed at different location inside corona extracted from sequence 4 of Fig. 3, upper part in southeast. The top profile (uncorrected for the slit broadening width is 0.11 nm) is taken in the inner corona where the slit crosses the big loops and arches at the foot of a big streamer; the bottom profile (width is now 0.18 nm) is taken at more than 1.05 R_⊙ from the limb (R >  2.05 R_⊙) and corresponds to the slit crossing the edge parts of the streamer near the boundary of the polar CH in the south. Some wing non-Gaussianity could be seen in the bottom profile.
