Figure 5
Left: scatter plots of parameters for ψBVG for the strong-peaks library from the β-lactamase E166Q (blue) and PsbO (orange) data sets. In both cases, peaks become smaller with increased scattering angle and remain relatively constant in size as a function of the azimuthal angle. The orientation of each peak is determined by the covariance, which oscillates with the azimuthal angle. Note that both data sets contain a strongly oscillating covariance, but only the PsbO curve is visible because they are overlaid. Right: three model bivariate Gaussians with different covariance (ρ) values. These demonstrate how covariance defines peak shape, which changes with φaz. Here, 2θ denotes the standard scattering angle (from the z axis) and the azimuthal angle, φaz, is the angle in the xy plane. |
