The 35-km interferometer at NRAO was used at 2.7 GHz during 1974–1979 to determine pulsar proper motions. Observations from each epoch were reduced to pseudo-position vector offsets which include both unknown, and constant, absolute position errors for the pulsars and their reference sources, as well as the time-varying proper motion of the pulsars. The coordinate system for which the errors in the offset components are independent is chosen. Proper motions resulting from a linear fit to the offsets for five pulsars are given in Table 1.
