Mean apparent HP width (without any deconvolution) versus spatial resolution for both HGBS filaments (red squares from Arzoumanian et al. 2019) and Hi-GAL filaments (black circles from Schisano et al. 2014). The red error bars correspond to ± the standard deviations of measured widths in each HGBS cloud. The black error bars correspond to ± the standard deviation of individual width estimates along each Hi-GAL filament in the Schisano et al. sample. The lines, curves, and yellow shading are the same as in Fig. 4.
