Top: sketch of S CrA N as inferred from our GRAVITY observations. The grey and blue ellipses display the positions of the continuum and the Brγ emitting regions, respectively. The red ellipse displays the inner truncation radius. The red dashed lines show the jet axis position with its uncertainty. Solid coloured lines show the orientation of the baselines along with their lengths and position angles. Middle: sketch of the S CrA system. Bottom: sketch of S CrA S as inferred from our GRAVITY observations in the continuum.
