Difference between several kinematic quantities in symmetric bins (l, d) and (−l, d) for model TWA1. The first three plots show the transverse velocity dispersion σ(V_T), skewness, and kurtosis of the transverse velocity distribution. The last plot shows the difference between the los velocity V_los compared to the expected value −2U_⊙cosl. We plot a black cross in bins where these quantities are statistically consistent with 0 with a 75% confidence, i.e. where they are compatible with an axisymmetric model. The rest of the notation is as in Fig. 6.
