Superposition of the model A lightcurves (continuous line) on the data points obtained from observations. All plots were drawn in the same coordinates: the x-axis is the rotation phase (in the range from 0 to 1), and the y-axis refers to the flux scaled to unity for the average brightness. We note that our convex model has problems with recreating sharp brightness maxima in LC03, LC05, and LC06 lightcurves. They are most likely caused by concavities on the asteroid surface.
