 TWINABS-2012/1 (Bruker,2012) was used for absorption correction.
 
For component 1:
 wR2(int) was 0.1488 before and 0.0683 after correction.
 
For component 2:
 wR2(int) was 0.1736 before and 0.0784 after correction.
 The Ratio of minimum to maximum transmission is 0.23.

Final HKLF 4 output contains 11652 reflections, Rint = 0.1278
