Comparison of stellar-density distribution constructed from data and different models for Auriga 12. The columns from left to right are the data, best-fitting model with constant p_DM and q_DM, and best-fitting model with p_DM(r) and q_DM(r) varying as a function of radius, r. The model with constant p_DM and q_DM cannot match the density distribution in all radial regions; there are significant residuals in the inner 20 kpc. The consistency between data and model improves with the model allowing variable p_DM(r) and q_DM(r).
