Abstract
Significant discrepancies in estimates of the Hubble constant are discussed in terms of the measurementproblem of calibrating the cosmological distance scale. It is shown that representing the Freedman–Robertson–Walker problem by a 3rd order Taylor expansion with respect to the criterion of minimal error inthe inadequacy is not optimal in terms of accuracy. An anisotropic 2nd order model based on the Heckmannrepresentation is more accurate.
