Example jet radial emission profiles (left) that can be created by the model, and corresponding differential visibility amplitudes and phases (middle, right) as a function of projected baseline length in the jet direction. The continuum is modeled as an unresolved point source, the flux ratio between the jet and the continuum is 0.5, and the wavelength is 2 μm. At the spatial scales probed by GRAVITY, more compact profiles (red) have smoother visibility curves, whereas more extended profiles (blue) show more significant substructure in the visibilities.
