Scientific paper

Spectra taken with the Palomar 60 inch echelle spectrograph are used to obtain 231 radial velocity measurements of 26 northern hemisphere Milky Way Cepheids with latitude between 15 and 140 deg and b below 5 deg. The typical accuracy of the Cepheid velocities is 0.8 km/s. Radial velocities of standard stars with accuracies of 0.6 km/s are also reported, and zero points determined from several systems are compared. The adopted zero point agrees with those of several other systems to + or - 0.1 km/s.
