After removal of a nearby bright source, we find that IOK-1 is not significantly detected in any of these infrared bands to m_3.6 ~ 24.00 and m_4.5 ~ 23.54 at 3 sigma. Fitting population synthesis models to the spectral energy distribution consisting of the upper limit fluxes of the optical to infrared non-detection images and fluxes in detection images, we constrain the stellar mass M* of IOK-1.
