One-dimensional spectra in ﹩{k}_{\perp }﹩ (a), ﹩{k}_{\parallel }﹩ (b) obtained by averaging in cylindrical coordinates as described in the text and in the Cartesian coordinates giving ﹩{k}_{\perp 1}﹩ (d), ﹩{k}_{\perp 2}﹩ (e) directions, the solid red line in (e) denotes the spectrum corresponding to the application of Taylor’s hypothesis. Figures (c) and (f) show the corresponding compensated spectra to (a), (b) and (d), (e) respectively.
