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 -2B_{nn} and -2E_{nn}, respectively, where B_{nn} and E_{nn} are the horizon vorticity and tendicity, respectively.
Now, here, you see, it takes all the running you can do, to keep in the same place. If you want to get somewhere else, you must run twice as fast as that.

The SXS project is a collaborative research effort involving multiple institutions. Our goal is the simulation of black holes and other extreme spacetimes to gain a better understanding of Relativity, and the physics of exotic objects in the distant cosmos.
The SXS project is supported by Canada Research Chairs, CFI, CIfAR, Compute Canada, Max Planck Society, NASA, NSERC, the NSF, Ontario MEDI, the Sherman Fairchild Foundation, and XSEDE.
