Notes. ^(a) Offsets of ellipse centre relative to stellar coordinates: proper motion corrected to IRCS 2009.89 (+0.186 s and -1 055 Perryman et al. 1997; van Leeuwen 2007) 014229 502, -53 44 28 06. The photospheric fluxes are 17 mJy at 70 m, 8 mJy at 100 m and 3 mJy at 160 m (cf. Fig. 2).
^(b) Flux for Gaussian ellipse with fitted FWHM to major and minor axis, 2a and 2b, respectively. Values in parentheses refer to de-convolved images.
^(c) Position angle measured from North over East.
^(d) Lower limit to the inclination, where i=90 refers to an edge-on geometry.
