Comparison of the temperature estimates for the selected clumps. In the left hand frames, the x-axis is the temperature derived from the total surface brightness. This is correlated with the minimum values within the apertures (frame b) and the values obtained with a local background subtraction (frame a). In the right hand frames the SPIRE temperatures (with background subtraction) are compared with the values obtained using the combination of SPIRE and AKARI data (λ > 100   μm) and with (frame c) or without (frame d) the subtraction of the local background.
