DEM maps reconstructed from the AIA images shown in Fig. 4. Rows, from top to bottom: the BP method (Cheung et al. 2015), the FIR method (Plowman et al. 2013), the SITES method (Morgan & Pickering 2019), the REG method (Hannah & Kontar 2012), and our proposed RML method. The images of each column correspond to the same temperature, which is reported in the top left corner of the first row panels. The same color map is shared by each of the images in the same temperature column, with different (logarithmic) scalings for the different temperatures.
