Dust temperature distribution calculated with RADMC-3D of MC2-HD at t_evol = 4 Myr for different numbers of photon packages. Differences between the distribution for 10⁹ and 10¹⁰ photon packages are less than 1 per cent for all dust temperature bins, and therefore we chose to use 10¹⁰ photon packages for all dust temperature calculations, as the computational costs for this highest value are still manageable.
