Sinking satellite history for different models and codes. Solid, dotted, and dashed lines correspond to BPM, Tree, and PM codes, respectively. The three codes are consistent with each other up to t = 1.3 t_dyn when small differences start to appear. The blue, red, and black colors correspond to NFW1, NFW2, and Plummer models simulations, respectively. The core stalling of the sinking satellite is evident in the Plummer model simulation.
