EnglishThe ratios of cross sections, Rb = σ(e+e− → bb)σ(e+e− → hadrons) and Rc = σ(e+e− → cc)σ(e+e− → hadrons), and the forward-backward asymmetries AFBbb and AFBcc, have been measured by the four LEP experiments at centre-of-mass energies close to the Z boson mass, using a variety of heavy flavour identification techniques and analysis methods. The procedure adopted to combine these measurements is described here. It takes into account the statistical and systematic correlations among the measurements and their interdependences in a χ2 minimization. The procedure is illustrated using published measurements.
