The acronym for the configurations is: 
"% of columns with substitution" - "column number" - "fraction of substitution in each column"

50_COL1_1 and 50_COL3_1 
have fully substituted sites in columns types 1 and 3 respectively but only 50% of the columns are substituted. 

100_COL2_1 
has 100% Ba substitution in columns type 2 and 100% of columns were fully substituted; 
this is because the unit cell only contains half the number of columns type 2 compared to columns types 1 and 3.

100_COL1_05 and 100_COL3_05 
have Ba substitution in 100% of columns type 1 and 3 respectively but only 50% of substitution in each column; 
substitution was performed such that Ba ions were placed to minimize Coulombic interactions.
