Dear Rietvelders, Do you know an efficient/precise way to determine the beam center for small angle scattering images in Fit2d? I have no data for standard sample. Circles are observed but very blurred, so it is hard to decide the beam center. There is a "contour plot" command but you cannot change the number of contours, so it is not very helpful. Sure one can zoom the image, print and draw some lines by hand, but that's not very professional. Any suggestions?
