HST vs. MUSE. Left: Hubble Space Telescope R-band image of NGC 7742. North is up and east is to the left. The 60′′ side is ~7 kpc wide in physical scale, assuming a distance to NGC 7742 of 22 Mpc. Right: MUSE reconstructed R-band image of NGC 7742, with the locations of 29 apertures overplotted. These apertures were used to extract the high-S/N spectra that provided the optimal stellar templates at the basis of our stellar kinematic and gas measurements. The apertures were designed to sample the nuclear, bulge, ring, and disk regions, allowing us to also investigate the SFH across these regions. The two foreground stars were masked out during the extraction of the aperture spectra.
