Figure 1: The modified black body spectrum representing the thermal dust emission for a range of dust temperatures from 15 to 45 K with a fixed dust emissivity spectral index of 1.8. This illustrates how the 100 μm emission (vertical dashed line) increases with increasing dust temperature, and hence how the AME emissivity defined relative to the 100 μm emission is biased by changes in dust temperature.
