Restoring the amplitudes. (a) Central section and isosurface representation of the final reconstruction before amplitude restoration; (b) after amplitude restoration with the exp(−6.75 Å2/d2) and exp(15 Å2/d2) envelope (where d is the resolution in Å); (c) after incorrect amplitude restoration which overemphasizes the low-resolution region but boosts the high resolution to the same extent. (d) Profiles of the reconstruction power spectra calculated before amplitude restoration (red line), after proper amplitude restoration (blue line) and after incorrect amplitude restoration (green line). The profiles are plotted on a log scale.
