Left: dust temperature radial profiles of K04166 (red), K04169 (yellow), and Miz-8b (blue). The dust temperatures were derived from Herschel Gould Belt survey data¹. The dashed colored lines correspond to line-of-sight averaged temperatures obtained from direct SED fitting, while dots and solid lines correspond to Abel-reconstructed dust temperatures. The colored shades represent the 1σ errors of the Abel-reconstructed temperatures. Right: radial profiles of β using the Abel-reconstructed temperatures. The color-code is the same as in the left panel. The gray dots show the β profiles corresponding to four different versions of the maps used to quantify systematic effects due to spatial filtering in the data. The gray-shaded area in both panels indicates radial distances below the half-beam width of 12″. The Abel transform is only performed for radial distances smaller than the dotted black vertical line in the left panel. On the upper x-axis the radial distance is in astronomical units assuming a distance of 140 pc for the Taurus molecular cloud.
