Abstract
The standard methods for determining the meridional flow on the Sun from the motions of tracers are shown to give an error related to the latitudinal nonuniformity of the tracer distribution. We suggest a simple method for eliminating this error. Using this method to determine the meridional circulation from the motions of sunspots brings the result into agreement with helioseismological data on the meridional flow. The discussed effects can be important for observations of meridional flows on stars.
