Phase improvement by iterative density modification
International Tables for Crystallography (2012). Vol. F, ch. 15.1, pp. 385-400 [ doi:10.1107/97809553602060000847 ]
... unit cell, including both the protein and the solvent. Zhang & Main (1988) systematically examined the electron-density histogram of several proteins ... taken from any known structure at the same resolution (Zhang & Main, 1988, 1990a). The ideal electron-density histogram can also be predicted by an analytical formula (Lunin & Skovoroda, 1991; Main, 1990a). The method adopted by Main (1990a) represents ...

Phase-extension schemes 15.3.4.3. Phase-extension schemes When performing phase extension, the order in which the structure factors are included will affect the final accuracy of the extended phases. The phases obtained from previous cycles of phase extension will be included in the calculation of new phases for the unphased structure ...
