The waveforms are calculated from numerical solutions of Einstein's equations for black-hole binaries that complete between six and ten orbits before merger. Along the equal-mass spinning branch, the spin parameter of each BH is $\\chi_i = S_i/M_i^2 \\in [-0.85,0.85]$, and along the unequal-mass branch the mass ratio is $q =M_2/M_1 \\in [1,4]$.
