Ellipticity, recovered inclination angle and recovered velocity dispersion for triaxial tracer + axisymmetric mass models and comparison with the axisymmetric tracer + mass models for the triaxial TNG-100 ETG sample. The inclination angle distribution is recovered using the conditional probability P(i|e), and the velocity dispersion is computed with axisymmetric JAM. We conclude that under the assumption of axisymmetric kinematics models, when the ellipticity is contributed by a triaxial tracer component, the kinematics recovery for the sample is unbiased.
