Phase-extension schemes
Cowtan, K. D., Zhang, K. Y. J. and Main, P.  International Tables for Crystallography (2012). Vol. F, Section 15.3.4.3, pp. 409-410 [ doi:10.1107/97809553602060000849 ]
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 ...

Density-modification modes
Cowtan, K. D., Zhang, K. Y. J. and Main, P.  International Tables for Crystallography (2012). Vol. F, Section 15.3.4.1, pp. 408-409 [ doi:10.1107/97809553602060000849 ]
Density-modification modes 15.3.4.1. Density-modification modes The following density-modification modes (specified by the MODE keyword) are provided by DM: (1) Solvent flattening: This is the most common density-modification technique and is powerful for improving phases at fixed resolution, but weaker at extending phases to higher resolution. Its phasing ...
