Overlay of the ellipse axes (orange) and the inner ring (white) as fitted in this work. The yellow cross marks the position of the central binary star. For reference we included the ellipse axes obtained by Uyama et al. (2020) based on the outer ring alone (dotted green). The underlying image is a two-band Qϕ composite of the IRDIS H-band (green layer) and the ZIMPOL Нα (blue layer).
