Phase determination at 6Å resolution 25.1.2.7. Phase determination at 6Å resolution These parameters were used to determine the phases of the protein reflections. A proportion of these phases were first determined by the graphical method suggested by Harker (1956), which had been used in the 6Å stage of sperm-whale myoglobin ...

Re-assessment of heavy-atom derivatives 25.1.2.6.4. Re-assessment of heavy-atom derivatives Given the three-dimensional data to 6Å resolution for the native crystals and the three derivatives, it was next possible to calculate three-dimensional difference Patterson maps for the derivatives using the terms as coefficients in the Fourier ...

Refinement of heavy-atom parameters
International Tables for Crystallography (2012). Vol. F, Section 25.1.2.5, p. 848 [ doi:10.1107/97809553602060000899 ]
Refinement of heavy-atom parameters 25.1.2.5. Refinement of heavy-atom parameters Refinement of the heavy-atom parameters was first performed by the use of Rollett's (1961) least-squares program on the MERCURY computer, using the values as structure amplitudes. This procedure gave satisfactory results for the K2HgI4, K2PdCl4 and MHTS ...
