 TWINABS-2012/1 (Bruker,2012) was used for absorption correction.
 
For component 1:
 wR2(int) was 0.1381 before and 0.0413 after correction.
 
For component 2:
 wR2(int) was 0.1090 before and 0.0453 after correction.
 
For component 3:
 wR2(int) was 0.1324 before and 0.0446 after correction.
 The Ratio of minimum to maximum transmission is 0.89.
