Additional Spots due to Inadequate Gain Normalization (in Diffractograms Obtained by Fourier Transformation)

Figure 4172 (a) shows a HRTEM image of an Au particle on a very thin amorphous W/WO2 film and (b) shows that Fourier transformation of the image (a) produced diffractogram. The additional spots from hexagonal fiberoptic array in (b) were due to inadequate gain normalization.
