Optical continuum images computed from MUSE (left) and MEGARA (right) in units of erg s⁻¹ cm⁻² (logarithmic scale). To obtain these images we considered a 60 Å wide continuum band (6105 − 6165 Å). The cross is the photometric centre, and the sizes of the different PSFs for MEGARA and MUSE data are indicated in the bottom left part of the figure (see also Sect. 2). As reference we show the field of view (dashed rectangle) and average seeing (14, bottom circle) for the WiFeS datacube analysed in D15. The black bar at the upper right represents 1 kpc (∼9″) at the redshift of NGC 1052 (see Table 1). Similarly, the white bar at the upper right, right panel, represents 400 pc (∼36).
