b-hadron production fractions at the Upsilon(4S) and Upsilon(5S)

This dataset contains the Heavy Flavor Averaging Group (HFLAV) averages of b-hadron production fractions at the Υ(4S) and Υ(5S). The averages take into account correlations among systematic uncertainties of different measurements and impose the constraint that the sum of the production fractions is equal to one.
