Kinetic temperature derived from the NH₃ data as a function of position along the blue filament (blue dots) and the red filament (red dots). Each data point is the median value of the kinetic temperature for points across the filament for a given position along the filament. The error bars indicate the median of the uncertainty. The dust temperature from Herschel data (Juárez et al. 2019) (beam size 37″), for a slice encompassing both filaments, is shown as a black solid line.
