Calculated physical properties for the filament. The panels show: mass-per-pixel (left); H₂ column density (middle); and volume number density (right) assuming a depth along the line-of-sight equal to the widest part of the filament (~8000 AU). The volumedensity is therefore likely an underestimate. The values are only calculated where the continuum is above 3σ (σ = 0.81 mJy beam⁻¹). The blackcontours show the continuum smoothed to the same resolution as the line data, starting at 5σ and increasing to 45σ in 10σ steps. The beam and a scale-bar are shown in the left and middle panels respectively.
