Starschurned outwards the most in the orbits integration (top 1%) from t = 1 to t = 2 Gyr (top three rows) or from t = 1 to t = 4 Gyr (bottom three rows). Left column: spatial distribution of these extreme migrators at t = 1 Gyr. Middle and right columns: spatial distribution at t = 2 or t = 4 Gyr in the orbits integration case and in the simulation. Each map is rotated such that the bar is parallel to the x-axis. The red circle is the corotation radius at t = 1 Gyr. The orange circle is the corotation radius at t = 2 or t = 4 Gyr. Black contours are the isocontours encompassing the local maxima of the effective potential with the pattern speed at t = 1 Gyr for the orbits integration panels, or at t = 2 or t = 4 Gyr for the simulation panels.
