1975MmRAS..78...75L Systematic Errors in the Velocities of Galaxies B.M.Lewis Abstract The 21-cm estimate V_21_ of the systematic velocities of 202 galaxies are compared with all available optical estimates for the same objects. The average difference between these measurements is shown to depend on the type of galaxy. An average estimate V_A_ of the optical velocity is derived by combining estimates from different observers. the differences (V_21_ minus V_A_) are normally distributed about zero, showing that despite the difference in precision, both the optical and 21-cm techniques produce statistically equivalent results. There is no dependence of the results on the abolute luminosity of the galaxy and no support is found for the existence of an anomalous redshift.
