Test with sources with radial temperature gradients. The average optical depth estimates (circles) and the source FWHM estimates (squares) are plotted relative to their correct values. The symbols correspond to 16 sources that are plotted against their central temperature T2. The 1-MBB and the 3-TMPL results are plotted in black and red. respectively. The shading shows the MCMC error estimates for the τ/τ0 ratio in the 3-TMPL fits.
