The uv-coverage for Epoch 2 of the GRAVITY 2017 observations. The colors represent the six different baselines, and the coverage in the radial direction corresponds to the different wavelength channels across the K band (2 − 2.5 μm). We also show the precessional axis of the jet and its precession cone as seen on sky. The projected baselines are sensitive to both the jet and the orthogonal directions.
