Cartoon (not to scale) representing a possible location of the extended continuum source in the central region of J0818+0601. The compact UV continuum source is located close to the center of the accretion disk. An outflow originates from the outer accretion disk. The BELR and the extended continuum source (hatched region) are located at the base of the outflow. Lines of sight to the observer, with an inclination i, are indicated. The compact continuum source is assumed to be microlensed, which is not the case for the BELR and extended continuum.
