Abstract
Data on the virtual dipole moment (VDP) is distributed nonuniformly with time, which significantly complicates qualitative and quantitative analysis of its evolution. In addition to the moving average method and median values, for the first time, a technique is presented for a quasi-uniform presentation of data (interpolation method), as well as results of calculating the evolution of the VDM by this method for the Phanerozoic.
