Probability of equilibria. All values of parameters are taken from Table 1, if not stated otherwise. Top left: distribution of the equilibrium rotation states over ω₁ and ω₂. Simulations for the DAMIT and radar shapes with the standard values of the relevant parameters (Table 1) are overplotted with the observed distribution in binaries. Top right: the same, but with κ = 0.1 ﹩{\rm{W}}\,{{\rm{m}}}^{-2}\,{{\rm{K}}}^{-1}﹩. Bottom left: the same, but with Q/K₁ = 100,000 and all values of C and B divided by 10. Bottom right: probability of equilibrium as a function of the mass ratio q. Different curves correspond to different values of relevant parameters. The first two lines are calculated for the radar and DAMIT shapes with the standard values of the relevant parameters from Table 1. The third line (“decreased YORP”) is computed for the YORP coefficients C and B twice smaller than in the radar database. For the remaining six lines the radar database is used, and all parameters are standard (Table 1), except of one parameter that is altered.
