Image Details
Caption: Fig. 7.
Top: Rotation of the pinwheel at each observing epoch from fits to data in Fig. 1, plotted as a function of the orbital phase. The dashed line gives a simple model of uniform angular velocity. Bottom: Residual between the data and the uniform model. Both panels have overplotted dotted lines giving examples of expected curves for elliptical orbits with eccentricity ﹩e=0.1﹩ and 0.2.
