Comparisons of map correlations of the optimized phases (φS) from the tests using the varied and the remaining reflections with map correlations from the tests using only the varied reflections for the calculation of map skewness as the target function for the search. The error bar on the plot indicates average and ±1σ map correlations obtained from five runs. The square marker indicates map correlation calculated using φB. (a) The 100 strongest reflections case. (b) The 500 strongest reflections case.
