Stellar surface density profiles along the x (left), y (centre), and z (right) axes of our model (dotted red line) compared to the analytic Sormani et al. (2022) model (crossed yellow line) including the overall best fit of an S22-type profile to our model (shown as a black solid line) and its various components, represented by a distinct colour-coded dashed line: disc in dark blue, bar₁ in pink, bar₂ in green, and bar₃ (i.e. long bar) in light blue.
