Fraction of the hydrostatic mass bias due to rotation (b) of the SRM (blue), ORM (red), and PRM (green) models, which we recovered from the true (dashed lines) and best-fit (points) LOS velocities using Eq. (33). The horizontal error bars indicate the extent of the region of the mock observations, while the vertical error bars indicate the 1σ errors on M_rot estimated from X-ray spectroscopy. The radius was normalized to r₅₀₀ as in Fig. 9, with the SRM radii, r₂₅₀₀, r₁₀₀₀, and r₅₀₀, indicated in the top axis.
