Diffraction limits (Ang.) and corresponding principal axes of the ellipsoid fitted to the
diffraction cut-off surface as direction cosines relative to the orthonormal basis (standard PDB
convention), and also in terms of reciprocal unit-cell vectors:
Diffraction limit #1: 1.948 ( 0.8822, 0.0000, 0.4709) 0.992 a* + 0.124 c*
Diffraction limit #2: 1.783 ( 0.0000, 1.0000, 0.0000) b*

Lowest cut-off diffraction limit:
2.139 at reflection 36 0 12 in direction 0.949 a* + 0.316 c*
Worst diffraction limit after cut-off:
2.171 at reflection 35 1 12 in direction 0.946 a* + 0.027 b* + 0.324 c*
Best diffraction limit after cut-off:
1.827 at reflection -36 22 10 in direction -0.830 a* + 0.507 b* + 0.231 c*
NOTE that because the cut-off surface is likely to be only very approximately ellipsoidal, in part
due to variations in reflection redundancy arising from the chosen collection strategy, the
directions of the worst and best diffraction limits may not correspond with the reciprocal axes,
even in high-symmetry space groups (the only constraint being that the surface must have point
symmetry at least that of the Laue class).

Baniso tensor: 67.26 63.77 67.08 0.00 4.82 0.00
NOTE: The Baniso tensor is the overall anisotropy tensor on Fs.
Delta-B tensor: 1.23 -2.27 1.04 0.00 4.82 0.00
NOTE: The delta-B tensor is the overall anisotropy tensor on Fs after subtraction of Beq from its
diagonal elements (so trace = 0). Neither this nor its eigenvalues shown below is used further in
any computation, including in anisotropy correction and deposition.
Eigenvalues of overall anisotropy tensor (Ang.^2), eigenvalues after subtraction of smallest
eigenvalue (as used in the anisotropy correction) and corresponding eigenvectors of the overall &
anisotropy tensor as direction cosines relative to the orthonormal basis (standard PDB convention),
and also in terms of reciprocal unit-cell vectors:
Eigenvalue #1: 71.99 9.64 ( 0.7139, 0.0000, 0.7003) 0.959 a* + 0.285 c*

Eigenvalue #3: 62.35 0.00 (-0.7003, 0.0000, 0.7139) -0.905 a* + 0.425 c*
The eigenvalues and eigenvectors of the overall B tensor are the squares of the lengths and the
directions of the principal axes of the ellipsoid that represents the tensor.
Delta-B eigenvalues: 5.96 -2.27 -3.69
The delta-B eigenvalues are the eigenvalues of the overall anisotropy tensor after subtraction of
Beq (so sum = 0).

The cut-off surface uses a different color scheme:
Unmeasured points are blue (inside the fitted 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: 2.14 [ = 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.
