Self-calibrated visibility amplitudes and phases as a function of uv distance from the RadioAstron observations of OJ 287 from April 24–25, 2016, at 22 GHz. The magenta points represent the fit to the data using the ehtim model derived from the imaging process. Reliable space-ground fringe detections were achieved up to a projected baseline length of 4.6 Earth diameters. The dot-dashed black line separates the ground-only baselines from those involving the SRT.
