Best single-dust models in order of increasing MSE, based on average of 250 μm and 500 μm residuals in Q=1−2 areas. Each model is labelled by the combination of the dust and cloud names and the $A_{\mathrm{V}}^{\text{ext}}$ value. The MSE markers and their colours indicate the model versions A-D. The 250 μm and 160 μm bias values are also plotted using the left y-axis, separately for the filament (Q=1) and the ridge (Q=2) regions. The 160 μm bias values are scaled by 0.1 for the plotting. The red crosses and the right y-axis show the bias in the predicted J-band extinction, b(τ_J)=(A(J, model)−A(J, obs.))/A(J, obs.) over the Q=1 area. A(J, obs.) is estimated using the extinction curve of the dust model in question and all stars in the filament region (Q=1). Red arrows indicate values outside the plotted range.
