Processed scanning SAXS data of specimen 100818 in the q-range corresponding to 140–200 nm on the left of each image pair, and the collagen-related signal on the right. The degree of orientation is defined as the ratio between anisotropic and isotropic scattered intensity, the mean orientation of the scattering signal is according to the color-wheel, the total mean scattered intensity relates to the abundance of nanometer-size scatterers, the deviation of the azimuthally integrated intensity from a cosine contains information similar to the degree of orientation, and the intensity exponent relates to the shape of the scatterers
