 The mean error should not exceed 0.005, and is usually caused by matrix
 changes during data processing.

 PART 2 - Reject outliers and establish error model

 Rejected reflections are ignored in the statistics and Postscript plots
 (except the detector diagnostics) and in the output .hkl file
 Before applying rejections there are:

   36423 total and   2208 unique reflections assuming Friedel's law

 Reflections rejected for which |I-<I>|/su >   3.00
 where:  su^2 = sigma(I)^2 + (  0.04000 <I>)^2  (sigma(I) from SAINT)

   35080 total and   2208 unique reflections left after |I-<I>|/su test

 su^2 = [K*sigma(I)]^2 + [g<I>]^2  where sigma(I) is from SAINT

 Error model 5: refine all K and overall g

 I/s(lim) is the limiting value of I/sigma(I) for a reflection of infinite
 intensity, and may be used as a criterion for data quality (Diederichs(2010),
 Acta Cryst, D66, 733-740. The above statistics are based on all non-rejected
 data, ignoring reflections without equivalents when estimating R(int) and K.
