Scientific paper
The ability to derive unique triaxial ellipsoid dimensions and a rotational pole for an asteroid is demonstrated on the basis of three stellar occultations. Two such occultations for Pallas are used to examine the locus of solutions falling along a curve in seven-dimensional parameter space. While the first occultation slightly overestimated the true size of the asteroid's outline, more plausible solutions are allowed within its errors. The occultation model is combined with speckle interferometric results. Pallas is more flattened, with a greater b/c ratio, and smaller c, than found in previous estimates.
