Spatial rendering of the derived properties of filamentary structure. Top: width of filaments’ mean radial profiles represented as colored data points and overplotted on the EM map. Compact bright regions tend to have smaller widths. Another notable region is DR 23, which has wider filamentary structure than average. Bottom: estimated density of each radial profile represented as colored data points and overplotted on the EM map. As expected, densities are highest in known star-forming regions.
