Notes. This gas-to-dust mass ratio is the ratio of the total gas mass over the total dust mass, and not the averaged Gdust over the map. That is the reason why the high spatial resolutions are defined. The errors account for the uncertainties on both the dust and the gas masses. We give also the 90% confidence interval. The convention for error display is defined in Eqs. (17) and (18).
