Direct measurement of the size, shape, and pole of 511 Davida with Keck AO in a single night

Using the high-quality data set of 165 images taken at 11 epochs over the 5.13 h rotation of the large C-type Asteroid 511 Davida, we find the dimensions of its triaxial ellipsoid model to be 357 ± 2 × 294 ± 2 × 231 ± 50   km . The images were acquired with the adaptive optics system on the 10 m Kec...
