Reconstructed image of the central 5.1 × 5.1 pc of NGC 1068. The elliptical beam, which was used to convolve the image, is shown in the lower left. Details of the reconstruction, which only allows positive sources, are given in Sect. 3.1. The central structures are robust to changing the reconstruction parameters. The fainter features towards the edge of the field, with fluxes close to the noise floor of ∼7 mJy beam⁻¹ rms (i.e. dark cyan in this colour scale), are uncertain.
