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).
Fraction of data inside cut-off surface: 88.7% ( 29137 / 32865)
Fraction of surface truncated by detector edges: 23.7% ( 454 / 1919)
WARNING: Diffraction of the input data has probably been truncated due to an inappropriate
(an)isotropic diffraction cut-off applied in previous processing, or the diffraction pattern may
have extended beyond the edges of the detector. In the latter case consider the possibilities of
either moving the detector closer or swinging it out, having carefully checked in the former case
that this will not create a risk of spot overlap.

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: 0.63 [ = 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.
