ME inversions of the Fe i 525.02 nm line synthesized with the help of MHD models. From top to bottom: magnetic field strength, inclination and azimuth, and LOS velocity. The left panels represent the results from the data degraded by telescope diffraction and CCD pixelation. The middle panels show the maps retrieved from the degraded profiles after convolution with a 6 pm wide filter and addition of noise. The right panels display the results obtained from the spatially and spectrally degraded observations with noise, sampled at five wavelengths points. Except for the reference, SNR = 1000 in all maps.
