Figure 4
Downsampling scheme. A region of a PILATUS 6M image with a Bragg reflection is shown (with numbers indicating pixel values). Raw data (left) are divided into blocks of pixels (indicated by red dashed lines). This occurs for both simulated and experimental data. The `conditioned' pixel value (right) is the square root of the maximum pixel value within each block, cast to an integer (floor operation). Block size varies according to the detector model; either 2 × 2 blocks (PILATUS 6M) or 4 × 4 blocks (EIGER 16M, JUNGFRAU 16M and Rayonix 340) were used.
