Scientific paper

We report 490 radial velocities for 16 Galactic Cepheid variables. The
typical uncertainty of a single velocity is +/-0.40 km s-1.
Comparison with published velocities shows excellent agreement. Two of
the Cepheids (Z Lac, S Sge) are known binaries and exhibit orbital
velocity changes in our observing interval.
