Emission from hot plasma and underlying magnetic field. The left two panels show the emission in the AIA channel at 94 Å and the Ti-poly channel of XRT on Hinode. The XRT image is taken during the Hi-C flight (at 18:54:48 UT). The right panel shows the HMI magnetogram. All panels cover the full field-of-view of the Hi-C data (cf. large rectangle in Fig. 2α). The inbox β indicates the region with the plage area hosting the small loop-like features as also displayed in Fig. 2β. The rectangle ε outlines the area covering hot coronal loops and moss as investigated by Testa et al. (2013). In their paper they display this region ε rotated counter-clockwise by 90° The moss area displayed in Fig. 2γ and marked here also by γ roughly corresponds to the moss region M3 of Testa et al. (2013), their Fig. 2. The yellow dashed line in the XRT image marks the edge of the XRT field-of-view. See Sect. 5.2.
