Followings are data after fitting images I got. These data are the sigma (rms) of the super-Gaussian fitting, for the electron beam image. They are in pixel unit.
From the data we can see that sigma (rms) of Y-projection are more spread, ie. has bigger standard deviation, than the of X-projection.
I think this is due to the beam profile in Y-projection contains less pixels than X- projection. (This is due to Y-projection observed with 45 degree angle, so Y-profile got squeezed).
So, Y-projection has less data for fitting, thus this creates bigger standard deviation for sigma (rms) value of the Y-projection.
