Study of possible biases on T_dust in a MBB fit and dependence of DH02 templates (e.g., Magnelli et al. 2014). DH02 templates are characterized by their α parameter. Black filled squares and open circles represent the values of T_dust associated with each DH02 template by fitting it with a MBB model with β = 1.5 or 2.0, respectively. The light blue grid maps the variation of T_dust as a function of redshift for each given template. The inset includes a zoom on a single template, aimed at showing the details of the dependence of the T_dust derivation on redshift. Each redshift point was artificially shifted by a small amount along the x-axis to avoid overlapping. Black crosses refer to the result obtained by applying Wien’s displacements law to DH02 templates.
