Azimuthally averaged disk eccentricity (see Eq. (4)) for different locations of the inner radius. Solid lines are averaged over 200 snapshots taken at the binary apastron during the simulation time from 1000 T_bin to 1200 T_bin. The shaded areas show the 1σ variations. The disk has a radius of ≈5 au, eccentricities at radii beyond that do not contribute to the disks eccentricity.
