GDRversus G0 (top), Σ gas (middle), and Σdust (bottom). We assumed a constant value of X(CO) = 4.0 × 1020 cm−2 (K−1 km s−1) to derive the gas mass in the disc of M 33. We colour-code the data with the oxygen abundance of each point obtained using the radial metallicity gradient from Bresolin (2011).
