Reference is made to a study by Margon (1982), who called attention to the small but significant deviations of the data from the predictions of the twin-jet model of Abell and Margon (1979) and Margon et al. (1979). The amplitude of these deviations is typically around 10 percent of the regular 164 d variations, whereas the accuracy in determining an individual Doppler shift is typically 0.1 percent. Margon proposed a stochastic jitter of the beam direction as a likely model. Since, however, the physical mechanism producing the beams has not yet been explained, there is no physical model for the beam jitter. The effect of the finite extent of the optically radiating region is investigated here. It is shown that these light travel time effects are small and cannot explain the 10-percent deviations. However, a slightly improved fit to the observational data can be obtained, leading to a best value for the optically luminous length of 1.3 x 10 to the 15th cm.
