Calculated mass precession, Δω_M = Δω_tot − Δω_SP, of S2 resulting in stellar profiles calculated numerically as a function of the assumed injected rate of CSs, η_B . Shown are the results for simulations that do not allow DCs (black) and those that include DCs at r ≤ R_col = 8 mpc (red). Also shown is the effective 1σ error estimated for the observationally inferred precession of S2.
