Enclosed mass profiles for Au-23-85-50 and comparisons with the true profiles. The black, red, and blue solid lines represent the true profiles of total mass, stellar mass, and dark matter mass, respectively. The corresponding dashed lines indicate the profiles of the best-fitting models, while the shadow regions denote the model uncertainties within 2σ confidence levels. The dotted vertical line represents the bar radius R_bar (half the bar length) from Blázquez-Calero et al. (2020).
