The spins have magnitude 0.95, are parallel to each other, but are anti-aligned with the orbital angular momentum. This simulation is described in a publication in Phys. Rev. D., in press. The paper can also be accesed at arXiv:1010.2777.
Note that aside from corrections that become important only near the time of merger, the spin function χ and scalar curvature R should agree well with -2Bnn and -2Enn, respectively, where Bnn and Enn are the horizon vorticity and tendicity, respectively.
Time writes no wrinkle
on thine azure brow,
Such as creation's dawn
beheld, thou rollest now.
