Notes. From left to right: (1) Galaxy name; (2) total stellar mass M*; (3) virial mass of dark matter halo M200; (4) optical radius Ropt; (5) inclination angle θT (from face-on 0° to edge-on 90°) and bar azimuthal angle φT (from end-on 0° to side-on 90°); (6) classification of the projected bar; (7) whether BP/X-shaped structure is considered in the modelling. We note that φT = 0° indicates the bar is perfectly end-on while φT = 90° means the bar is perfectly side-on.
