typical galaxy scale, so that our data allow us to infer for all targets whether the gas is confined to within the AGN host galaxy or extends beyond. MRC 2104$-$242, MG 2037$-$0011, and NVSS J2135$-$3337 fortuitously have nearby bright stars that served as natural guide stars for adaptive-optics assisted observations. For those galaxies, we obtained high-resolution observations with a spatial resolution of about 0.4 ($\sim$3 kpc). The spatial resolution for these sources is limited by the pixel size. We used the largest pixel size also for the adaptive-optics data, because we wanted to reach the highest possible sensitivity to the lowest surface-brightness gas in our sources.
