Optical-to-MIR (black dots), optical-plus-MIR (red dots), optical (blue dots), and MIR (yellow dots) pseudo-bolometric lightcurves after day 200, compared to the bolometric lightcurve (black dashed line), deposited ⁵⁶Coγ-ray (blue dashed line) and positron (red dashed line) luminosity, and deposited ⁵⁷Co luminosity (yellow dashed line) for the preferred steady-state NLTE model (12F). The lightcurves have been normalized to the radioactive decay chain luminosity of 0.075 M_⊙ of ⁵⁶Ni.
