R Aqr I-band Stokes Q (left) and U (right) signal measured for the unsaturated PSF in the narrow-band (nb) Cnt820 filter (upper left), for the saturated broad band I_PRIM filter (middle left), and deep coronagraphic observations for the I_PRIM filter and slow polarimetry mode (lower left and large frame). The cut for the count profiles of Fig. 33 is shown in the large Q-frame. Units are in pixels of 3.6 mas.
