[Users] QuasiLocalMeasures BH Spin

Hi All,

I'm trying to reproduce the testbed BBH results in Etienne et al. 2009: https://arxiv.org/abs/0812.2245

I'd like to calculate the final Kerr black hole spin using the ratio of the polar and equatorial circumferences. QuasiLocalMeasures qlm_scalars gives several spin-related quantities:

qlm_spin_guess qlm_spin qlm_npspin qlm_wsspin qlm_cvspin qlm_coordspinx, qlm_coordspiny and qlm_coordspinz.

How are these related? Are any of them calculated using the Kerr formula?

Also: what's the difference between qlm_polar_circumference_0 and qlm_polar_circumference_pi_2?

Thanks,

Gwyneth
