Terrible ;) For R2eff, the correlation is 2.748 and the points are spread out all over the place. For I0, the correlation is 3.5 and the points are also spread out everywhere. Maybe I should try with the change from:
relax_disp.r2eff_err_estimate(chi2_jacobian=True) to: relax_disp.r2eff_err_estimate(chi2_jacobian=False) How should this be used?
