A simple numerical procedure is described for measuring the distance XY in the generalized reciprocal method when there are significant measurement errors in the refracted arrival times. It is applicable when the XY value is of similar magnitude to or less than the receiver spacing. Such conditions frequently occur in using the reciprocal or generalized reciprocal methods to estimate static corrections from first‐break times measured in multifold seismic reflection profiling. The use of the method is illustrated with data from both deep and high‐resolution seismic reflection profiles.
