Fig. 1. Toutatis radar images. Goldstone low-resolution images from 2-18 December (top three rows) and Arecibo images from 14-19 December (bottom row) are plotted with time delay increasing toward the bottom and Doppler frequency increasing toward the left. On the vertical sides, ticks are 2 microseconds apart. Two horizontal sides have ticks separated by 1 Hz for Goldstone and 0.28 Hz for Arecibo; those intervals correspond to a radial velocity difference of 18 mm/s. Gray scales were designed to show the extent of the delay-Doppler distributions.
