Analysis of whistler waves detected by Solar Orbiter RPW on 2020 July, 22nd around 14:03. Panels a–d: The X component is in black, Y is in red, and Z is in yellow (spacecraft reference frame). Panel a: Background magnetic field B₀. Panels b and c: Waveforms of the magnetic Bw and electric Ew fields. Panel d: X component of the Poynting vector (S_X). For Panels c and d, we used an effective length of the electric antennas equal to 6 m. Panels e–i: Analysis of the wave packet delimited by vertical dotted lines. Panel e: Ratio of the magnetic power spectrum to the median power spectrum of the day (black) and the same for the electric field (green, with the Y and Z components only). Panel f: Polarization (Lp in orange), planarity (F in black), and propagation angle (θ in purple). Panel g: Phase shift between Bw_x and Bw_y (in the wave reference frame with k = kz, see Sect. 2.1). Panel h: Spectral coherence between different components. Panel i: Phase of the X component of the Poynting vector φ_SX.
