    any computation, including in anisotropy correction and deposition.

    The fitted cut-off surface uses a different color scheme:
    Unmeasured points are blue (inside the surface) or cyan (outside).
    Unobserved points are red (in) or green (out).
    Observed points are orange (in) or white (out).
    The fitted surface is magenta.
    
    Anisotropic S/N ratio:  9.46        [ = max_h | exp(4 pi^2 s_h.delta(B)s_h) - 1 | <I_h/sd(I_h)> ]
    
    The 'anisotropic S/N ratio', unlike the 'anisotropy ratio' or the 'fractional' anisotropy shown
    above, in addition to the anisotropy of the B tensor, takes both the diffraction and the local mean
    I/sd(I) into account.

  • Normalised scores from a panoply of hemihedral twinning tests.
  • For each test, the most likely hemihedral twin fraction based on the data is the one corresponding to the lowest normalised score (i.e. like the R value).  For all the distributional tests (i.e. those of the form P(x)), the raw score before normalisation is the Kullback-Leibler divergence from the theoretical to the observed probability density.  For the non-distributional Britton and Fisher & Sweet tests, it's the count of extra negative intensities obtained by detwinning the data using each possible twin fraction.  Note: click image to enlarge.
