Upper panel: Lyα profile of Haro 11 C, in approximate units of the surrounding continuum level. The full line indicates the measured values smoothed by a 5 px flat kernel; surrounding shading encloses the ﹩\pm 1\sigma ﹩ error band (mostly comparable in width to the line width). Middle panel: black steps show the averaged LIS line profile, smoothed by a 5 px kernel. Surrounding gray shading denotes the ﹩\pm 1\sigma ﹩ confidence band. Lower panel: same as middle panel, but for the Si IV transitions.
