Misalignments Ψ(R) (full circles) as function of the major axis distance for FRs and SRs. The horizontal solid line shows the Ψ = 0 axis. The light blue stars are the Ψ values calculated on PA_kin from the kinemetry of Foster et al. (2016), Krajnović et al. (2008 and 2011); for the other galaxies the PA_kin is not previously available in the literature. The red dot-dashed vertical lines report the radial transition range R_T ± ΔR_T, see Sect. 8.6. Signatures of triaxial halos are seen in NGC 0821, NGC 1344, NGC 1399, NGC 3377, NGC 3379, NGC 3608, NGC 3923, NGC 4365, NGC 4374, NGC 4472, NGC 4473, NGC 4494, NGC 4552, NGC 4636, NGC 4649, NGC 4742, NGC 5128, NGC 5846, and NGC 5866.
