I would like to know how the columns EXP_NORM	REF_NORM were created in this dataset


I know how the previous columns 
EXP_46561_532	REF_46561_635	RATIO
were calculated. But cannot find how they got the next column, I tried subtracting mean, median values from the column but couldnt figure it out.

Thanks in advance
