Map of the SPHERE/ZIMPOL Hα line observation of R Aqr taken in the N_Ha (FW0) filter on Oct. 11, 2014. The field is divided into three different gray scale regions ranging from 0 to 1000 ct pix-1 frame-1 for the central binary, 0 to 100 for the inner jet region rRG< 0.72′′, and 0 to 10 for the outer jet region rRG> 0.72′′. The red giant is at the zero point of the coordinate system. There is a small angle offset of 2 deg of the sky N orientation in a counter-clockwise direction with respect the (vertical) y-direction. A weak instrumental spike from a telescope spider is present at a position angle of about −105° indicated by a small arrow outside the frame.
