Intensity obtained from Fe X 184.54, Fe XII 186.88^*, Fe XI 188.23, Fe XII 195.12, and Si X 258.37^*, 261.04 Å spectral lines along the coronal loop (left panel) and quiet Sun region (right panel) with height. The intensities are recalibrated using the method of Del Zanna (2013). The asterisks denote respective spectral lines are density sensitive. Horizontal lines denote expected level of scattered light as per Ugarte (2010).
