Fit to the spectral energy distribution of the quasar J0015+1842 using photometric points from SDSS and WISE (black squares). The solid (resp. dotted) blue line shows the reddened (resp. unreddened) quasar type I template from Polletta et al. (2007). The NOEMA continuum measurements at 3.08 and 3.67 mm are represented by the red circles with error bars, and the associated constraint on the cold dust emission component assuming T_d = 60 ± 20 K is shown in green.
