SED fitting of WISE J1042+1641. Filled circles represent the observational data from the SDSS (black), 2MASS (red), and WISE (green). The 5σ upper limit from AKARI is denoted as a blue arrow. The best-fit SED is denoted with the black solid line. Different components are also shown: unattenuated stellar emission (green line), attenuated stellar emission (red line), nebular emission (pink line), SF-heated dust emission (light blue line), and AGN emission (blue line).
