Fourier transforms
International Tables for Crystallography (2012). Vol. F, Section 15.3.5.4, p. 411 [ doi:10.1107/97809553602060000849 ]
Fourier transforms 15.3.5.4. Fourier transforms For simplicity of coding, all Fourier transforms are performed in core using real-to-Hermitian and Hermitian-to-real fast Fourier transforms (FFTs). The data are expanded to space group P1 before calculating a map and averaged back to a reciprocal asymmetric unit after inverse ...

Solvent-mask determination
International Tables for Crystallography (2012). Vol. F, Section 15.3.5.2, p. 411 [ doi:10.1107/97809553602060000849 ]
Solvent-mask determination 15.3.5.2. Solvent-mask determination If the user does not supply a solvent mask, the solvent mask is calculated by Wang's (1985) method, using the reciprocal-space approach of Leslie (1987). A number of variants on this algorithm are implemented; however, the parameter that affects the quality ...

Multi-crystal averaging
International Tables for Crystallography (2012). Vol. F, Section 15.3.5.7, p. 412 [ doi:10.1107/97809553602060000849 ]
Multi-crystal averaging 15.3.5.7. Multi-crystal averaging The multi-crystal averaging calculation in DMMULTI is equivalent to several single-crystal averaging calculations running simultaneously, with the exception that during the averaging step, the molecule density is averaged across every copy in every crystal form. This average is weighted by the mean ...
