Comparison between the temperature derived from the maps (i.e., T_1D, 500) and the global temperature (i.e., T_spec) obtained by fitting a single spectrum extracted within R₅₀₀. In each subplot the text in magenta indicates the weighting used to recover T_1D, 500 from the maps, while the values of μ and σ indicate the median of the distribution and its dispersion. In blue we show the results using the maps obtained with S/N=30 while in red we show the ones obtained with S/N=50.
