Distribution of the misalignments Ψ = PA_kin − PA_phot at 1 R_e as a function of the ellipticity for both TNG100 and TNG50 galaxies. Data points are color coded according to their intermediate to major axis ratio p(1 R_e); open symbols are SRs, filled symbols are FRs. The solid lines show the scatter of the misalignments as a function of the ellipticity for the TNG galaxies, calculated on the mirrored (Ψ, −Ψ) data. The dashed lines show the scatter for the MANGA and Atlas3D galaxies. Red lines are for the SRs, blue lines for the FRs. The triaxiality of the IllustrisTNG FRs is consistent with the near-alignment of their kinematic and photometric position angles.
