Refinement of the direct beam position applied to ferritin scattering data. (a) `Pizza slicing' of the mean detector image into eight equal azimuthal sectors. Azimuthally integrated intensity profiles I(q) for each sector are shown (b) before and (c) after optimization. Improved overlap after refinement indicates a more accurate beam-centre determination. |
