Convergence of radiative and advective timescales. Radiative timescales in run RADL27k0.01LONG converge rapidly in about 4 orbits, outside the smoothing radius at 0.25 r_H. Little change occurs between 8 to 50 orbits. After 8 medium resolution orbits, the restart at high resolution, labeled hr in the legend, does not alter t_diff outside 0.1 r_H. Advective timescales also settle quickly. We note, however, that approximately 4 orbits at high resolution are required to capture the increased vertical advection timescale around 0.2 r_H (run RADL27k0.01).
