Comparison of the errors in the A and B parameters of the β(T) relation, comparing cases with 50 or 500 observed sources. The methods of analysis are χ², SIMEX, BM, MC, and HM(S). For each method, two boxplots are shown, the 50-source case on the left and the 500-source case on the right. The observations consist of data in Herschel bands at wavelengths 100–500 μm and with a relative noise of 10%.
