Comparison of disc eccentricity (top) and disc longitude of pericentre (bottom) for the standard model. The disc eccentricity was calculated by summing over the whole disc (R₂ = R_max in Eq. (18)), whereas the disc longitude of pericentre was calculated only for the inner disc (R₂ = 1.0 au in Eq. (19)). The π-shift of the green curve in the bottom panel is explained in the text. We used a resolution of 512 × 580 grid cells for Pluto simulations and for Fargo and Rh2d simulations a resolution of 448 × 512.
