Figure 5. Initial deconvolution improves the estimate of the parameter by enhancing the peak occurrence in the correlation .

Correlation result for a sample (a) without and (b) with initially deconvolved raw data O_j,m. In the first case, there is no peak in the region where is expected (white dashed inset). In the second case the occurrence of the peak is clearly visible. (c) If an annular mask is applied to the correlation in (b) to highlight the region of interest, the peak can be extracted automatically by detecting the maximum in this region.
