Time evolution of Cen A at 8.4 GHz. Contour clean images, restored with a common beam of (3.33 × 0.78) mas at PA = 26.3°. The contours indicate the flux density level, scaled logarithmically, and increased by a factor of 2, with the lowest level set to the 5σ-noise-level. The positions and FWHMs of the Gaussian modelfit components are overlaid as black circles (for model parameters see Table A.1).
