Top panels: (first row) T for NOAA AR 12480 at log(τ) = −4 provided by STiC (left), IRIS² (center), and deepIRIS² (right). Middle panels: uncertainties for these methods. Bottom-left panel: χ²-map associated to STiC results. Bottom-middle and bottom-right panels: uncertainty multiplication factor (UMF_T) for IRIS² and deepIRIS² methods. Regions of interest (RoIs) are marked with squares in the center panel of the top row. The animation runs from log(τ) = −6 to −0.8.
