Top: position of β Pic b together with errors bars measured on 3 different cADI images (mean of the residuals). The full lines correspond to mean cADI data, the dashed lines correspond to measurements on median cADI data. Dashed horizontal lines shows the min and max PAs of the main disk and dotted ones the min and max PAs of the warp component. Conservative error bars have been taken into account. Middle: idem for sADI data. Bottom: idem for rADI data.
