 TWINABS-2012/1 (Bruker,2012) was used for absorption correction.
 
For component 1:
 wR2(int) was 0.1076 before and 0.0562 after correction.
 
For component 2:
 wR2(int) was 0.1386 before and 0.0624 after correction.
 The Ratio of minimum to maximum transmission is 0.79.

Final HKLF 4 output contains 82547 reflections, Rint = 0.0412
