Caravan-Submm, Black Hole Imager in the Andes

Figure 9

From Miyoshi et al. [8]: the visibility amplitudes of three image models as function of projected baseline: (a) the case of , (b) the case of , and (c) the case with no black hole or the scattering effect is still dominant. The functions of (a) and (b) have null value points that indicate the existence of the central black shadow. The noise level of present engineering performance is shown by the red horizontal line. The red point with error bar is the visibility amplitude measured by Krichbaum et al. [9].
