Gas-dust correlation plots of the velocity components “b”,“c”, and “d” of the filament candidate G333.297+00.073 (see Figs. 3, 5, and 6). The blue line gives the one-to-one correlation. The green area indicates values above the σ_gas limit. The red line shows the fitting result, and the area within the dashed red lines marks the ± σ_cor surrounding. p_cor,gas is estimated from the overlap of these areas.
