Dependence of filament parameters on the column density and inclination of model filaments. The cyan, blue, and red curves and symbols show, respectively, parameter estimates at column densities N(H₂) = 3 · 10²² cm⁻², N(H₂) = 10²³ cm⁻², and N(H₂) = 3 · 10²³ cm⁻² as functions of the filament inclination. Zero inclination corresponds to the perpendicular view direction and 70.5 degrees to a factor of three higher line-of-sight column density. For reference, the horizontal black dashed lines show the zero-inclination values for the three column densities and additionally for N(H₂) = 10²⁴ cm⁻² (the uppermost lines).
