Active region observed by the Hinode satellite on 14 Nov. 2007. The left panel shows the X-ray emission observed by XRT together with the field-of-view of EIS (green dash-dotted square) and SOT-NFI (red dashed rectangle). The right panel displays a line-of-sight magnetogram (saturation level: ±300 G) of the active region that is smoothly embedded in a quiet Sun carpet (see Sect. 3.2). We use only the co-aligned AR core area (blue solid square) for our analyses. The circles and lines indicating various loop structures are co-spatial with those in Fig. 2.
