The refinement method is indicated along the horizontal bar in the igure sing the code: RS(m.i.r.). real-space mehod on .i.r. aps; S(ZF,-FJ. real-space method n 2F- F, aps; DDF, differential difference Fourier; Lt51, least-squares series 1; S2, least-squares series 2. The -factor is defined in the onventional manner as H = [[F,,[ - IF,II/x IF,], ere F, s an observed structure factor and F, is calculated tructure factor. 		Figure 4.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB code is shown on the right.
