Einstein Toolkit version:
qc0-mclachlan.par in einsteinexamples with the additional parameter
TwoPunctures::par_S_plus  = +0.3
Problem: The diagnostic
qlm_spin returns a spin of 0, whereas the expected one should be 0.3.
If instead of
TwoPunctures::par_S_plus  = +0.3 one sets
TwoPunctures::par_S_plus  = +0.3,
qlm_spin is correctly
This happens because QuasiLocalMeasures finds in both cases the rotational Killing vector d/dphi (as seen setting
QuasiLocalMeasures::veryverbose = yes), which is correct in the second case (when the axis aligned with the z-direction), but doesn't sound right when the rotation is with respect to the x-axis.
gradient does not change the outcome.
