Consistency of the gas-to-dust mass ratios. The two trends show the gas-to-dust mass ratio as a function of the spatial resolution, for each model. We also display the 90% confidence interval for the “standard model”, with dashed lines. The yellow and purple error bars, with the star symbol, represent the uncertainities on and , respectively (Table 5; solid line: 50%; dashed line: 90%). The purple, green and yellow solid lines show the central values of , and , respectively. The yellow filled area represents the gas-to-dust mass ratio range below the central value of the limit ratio .
