Figure 2
Angle-averaged pattern produced by summing over all frames in the low-fluence data set. The direct beam goes through the center of the beamstop and the rotation axis is vertical. Note the radial streaks caused by polychromaticity of the beam due to Bremsstrahlung. These streaks form arcs near the vertical rotation axis due to the curvature of the Ewald sphere. The white gaps in the image are the spaces between the six detector tiles in the 2 × 3 tiled array of the MMPAD detector.
