N2 - A technique for constructing optimally smooth model rotation curves has been applied to complexes of HII regions and molecular clouds, yielding a Galactocentric distance of R0 = 8.3 ± 0.8 kpc. The residual motion of the Local Standard of Rest with respect to these objects is 3.4 ± 1.3 km s-1 in the direction of the Galactic anticenter and 4.1 ± 2.1 km s-1 in the direction of the Galactic rotation. Ignoring the azimuthal component of this motion results in substantial underestimation of R0. Data on the rotation of neutral-hydrogen and HII-region subsystems and the derived value of R0 are used to estimate the Oort constant A = 16.2 ± 0.6 km s-1 kpc-1 and the parameter AR0 = 135 ± 5 km s-1.
