Scatter plots of the polarisation efficiency as a function of the visual extinction in magnitudes for the optical data (in black) and for the FIR data (in red, only one point every other is shown), in logarithmic scale. The best fit to each dataset, as described in the main text, is shown with the pink and blue dashed curve, respectively. The best-fit equations are also shown in the bottom left and top right corners.
