Results of the mock analysis performed for polar dust extinction in the V-band, A_V (top panel) and polar dust temperature (bottom panel). The exact values (x-axis) are plotted against the values measured by fitting the simulated datasets (y-axis). The open circles refer to the SMC extinction curve, the filled circles to the G04 extinction curve. The linear fits are shown as solid (G04) and dotted (SMC) lines. The statistical significance of the measure is color-coded.
