Comparison between the input atmosphere (top) and the atmosphere inferred with DeSIRe (bottom) for the inversion test described in Sect. 4.4. From left to right, we show the temperature, the LOS velocity, and the magnetic field. The FOV corresponds to the horizontal line enclosed within the squared region in Fig. 2. Abscissae correspond to the X axis in Fig. 2, and ordinates show the evolution with the height of the atmospheric parameters.
