Amplitude (top) and phase (bottom) of the simulated radio galaxy. In the first step, the representation of the radio galaxy in Fourier space was calculated by Fourier transform. Then the complex values were transformed to amplitude and phase utilizing Euler’s formula. To mimic an observation with a radio interferometer, the images were sampled using the (u, v) coverage of a simulated observation with the VLBA. The remaining information is displayed in color, all dropped information is grayed out.
