Same as Fig. 14, but for polar radial profiles of Metis and UVCS. Top panel: UVCS data and intensity profile obtained for polar observations and summed with the contribution of the interplanetary H I Ly-α line intensity (IP, dotted line) are depicted as gray circles and blue solid line, respectively. The dashed blue line shows the extrapolation of the UVCS profile up to 9.5 R_⊙ for comparison. Bottom panel: symmetrical logarithmic scale of the vertical axis for better visualization; i.e., it is logarithmic in both the negative and positive directions with a linear scale between −10⁹ and 10⁹ photons cm⁻² s⁻¹ sr⁻¹.
