Animations of the rotational model with the convex shape model showing the fit to lightcurves from April 20 (a), April 22 (b), May 9 (c), and May 7 (d), respectively. Similar to the LAM model with an ellipsoidal shape, the angular momentum vector L almost lies within the image plane, with the angles from the line of sight 102^∘, 101^∘, 89^∘, and 91^∘ in the four epochs, respectively. Animations of all panels are available. The observational time intervals and the real-time duration of the animation are the same as those given for Figure A1.
