WI and GCV in Europe – TSO results Frequency distribution > The EN 437 range has been divided in steps of 0.5 MJ/m 3 . > For each data set, the number of values found within each step is calculated. > By grouping data sets with a common feature (supply source) an approximate frequency histogram can be derived.
