'''A word of warning''': even if the internal quality indicators (R-factors) are better when using this feature, there is no guarantee that the resulting intensities will actually be better suited for your purposes than those obtained without it. In particular, extrapolating to the ends of the dose interval (0 dose and full dose) decreases the precision of the intensities. | '''A word of warning''': even if the internal quality indicators (R-factors) are better when using this feature, there is no guarantee that the resulting intensities will actually be better suited for your purposes than those obtained without it.

=== Optimal values of dose, for interpolation === | |||
The optimal points for interpolation are near 1/4 and near 3/4 of the total dose. Details are published in [http://dx.doi.org/10.1107/S0021889808036716 Diederichs, K., Junk, M.
