Calculations of fitting parameters, describing electrostatic potentials $U\left(r\right)$ and atomic densities $\rho \left(r\right)$ in a simple analytical form, are presented for neutral atoms with the nuclear charges $Z=93$–120. The data are obtained based on calculations of wave functions in the relativistic Dirac-Fock-Slater approximation with the extended distribution of the nuclear charge. The $U\left(r\right)$ and $\rho \left(r\right)$ functions are approximated by the sum of three Yukawa potentials with six fitting parameters as has been done for $Z=1–92$ by other authors.
