Refinement of Parameters of Six Selected Galactic Potential Models
  This paper is devoted to the refinement of the parameters of the six
three-component (bulge, disk, halo) axisymmetric Galactic gravitational
potential models on the basis of modern data on circular velocities of Galactic
objects located at distances up to 200 kpc from the Galactic center. In all
models the bulge and disk are described by the Miyamoto--Nagai expressions. To
describe the halo, the models of Allen-Santill\'an (I), Wilkinson-Evans (II),
Navarro-Frenk-White (III), Binney (IV), Plummer (V), and Hernquist (VI) are
used. The sought-for parameters of potential models are determined by fitting
the model rotation curves to the measured velocities, taking into account
restrictions on the local dynamical matter density $\rho_\odot=0.1 M_\odot$
pc$^{-3}$ and the vertical force $|K_{z=1.1}|/2\pi G=77 M_\odot $ pc$^{-2}$. A
comparative analysis of the refined potential models is made and for each of
the models the estimates of a number of the Galactic characteristics are
presented.
