Figure 1
X-ray powder diffraction profile from the final Rietveld refinement of whale metmyoglobin. Observed intensities are shown as crosses (+), calculated and difference curves as lines, and reflection positions for (NH4)2SO4 and protein are shown as tick marks (|). The background intensity found in the refinement has been subtracted from the observed and calculated intensities for clarity. [Reproduction of Fig. 4 from Von Dreele (1999).] |
