Summary of measured TIs (units: J K⁻¹ m⁻² s^−0.5) from a variety of sources. Measurements in black represent previous published works and coloured bars represent this work. From Left to right, these measurements represent the TI from: (a) Spitzer observations (Lamy et al. 2008); (b) a thermophysical model applied to light curve observations (Lowry et al. 2012); (c) MIRO observations by Gulkis et al. (2015); (d) MIRO observations by Schloerb et al. (2015); (e) MIRO observations by Choukroun et al. (2015), with TI from the millimetre channel in black and TI from the submillimetre channel in grey; (f) MUPUS observations, with average represented in white (Spohn et al. 2015); (g) VIRTIS observations (Leyrat et al. 2016); (h) MIRO observations from this work in Seth region, with TI from the millimetre channel in dark green and TI from the submillimetre channel in light green (horizontal lines represent upper or lower bounds); (i) MIRO observations from this work in Aten region; (j) MIRO observations from this work in Ash region; (k) MIRO observations from this work in Ash region; (l) MIRO observations from this work in Aten region; and (m) VIRTIS observations from this work; the best-fitting value is indicated in white.
