Light-curve amplitude vs. spin rate. The symbols are the same as in Fig. 3. The dashed, dot-dashed, and dotted lines represent the spin-rate limits, \(P \sim 3.3 \sqrt{(1 + \Delta m)/\rho }\) (Pravec and Harris 2000), for rubble-pile asteroids with a bulk densities of \(\rho =\) 3, 2, and 1 g cm−3, respectively. Note that the asteroids of \(D < 0.2\) km are not included in this plot.
